| deepseekr1 | To find the equation of the tangent line to \( y = x + e^x \) at \( x = 0 \): 1. **Calculate the point on the graph at \( x = 0 \):** Substitute \( x = 0 \) into the function: \( y = 0 + e^0 = 1 \). The point is \( (0, 1) \). 2. **Find the derivative (slope of the tangent line):** The derivative of \( y = x + e^x \) is: \( \frac{dy}{dx} = 1 + e^x \). At \( x = 0 \): \( \frac{dy}{dx} = 1 + e^0 = 1 + 1 = 2 \). The slope \( m = 2 \). 3. **Use point-slope form to write the equation:** With \( m = 2 \) and point \( (0, 1) \): \( y - 1 = 2(x - 0) \), simplifying to \( y = 2x + 1 \). Comparing with the options, **A. \( y = 2x + 1 \)** matches. **Answer:** A |

| GPT-4o | To find the equation of the line tangent to the graph of \( y = x + e^x \) at \( x = 0 \), we need to determine the slope of the tangent line at that point and the y-intercept. 1. **Find the slope of the tangent line:** The slope of the tangent line is given by the derivative of \( y = x + e^x \). \[ \frac{dy}{dx} = 1 + e^x \] Evaluate the derivative at \( x = 0 \): \[ \frac{dy}{dx} \bigg|_{x=0} = 1 + e^0 = 1 + 1 = 2 \] So, the slope of the tangent line at \( x = 0 \) is 2. 2. **Find the y-intercept:** To find the y-intercept, we need the y-coordinate of the point where the tangent line touches the curve at \( x = 0 \). \[ y = x + e^x \bigg|_{x=0} = 0 + e^0 = 0 + 1 = 1 \] So, the point of tangency is \((0, 1)\). 3. **Equation of the tangent line:** The equation of a line in slope-intercept form is \( y = mx + b \), where \( m \) is the slope and \( b \) is the y-intercept. Here, the slope \( m = 2 \) and the point of tangency gives us the y-intercept \( b = 1 \). Therefore, the equation of the tangent line is: \[ y = 2x + 1 \] So, the correct answer is: A. y = 2x + 1 |

| llama3.1-70B-Instruct | To find the equation of the line tangent to the graph of y = x + e^x at x = 0, we need to find the slope of the tangent line and the point of tangency. First, let's find the derivative of y = x + e^x, which is y' = 1 + e^x. Next, we evaluate the derivative at x = 0 to find the slope of the tangent line: y' (0) = 1 + e^0 = 1 + 1 = 2. Now, we need to find the point of tangency. We can do this by plugging x = 0 into the original equation: y = 0 + e^0 = 1. So, the point of tangency is (0, 1). Using the point-slope form of a line, we can write the equation of the tangent line as: y - 1 = 2(x - 0). Simplifying, we get: y = 2x + 1. Therefore, the correct answer is: A. y = 2x + 1 |

| DeepSeek-Coder-V2 | To find the equation of the line tangent to the graph of \( y = x + e^x \) at \( x = 0 \), we need to follow these steps: 1. **Find the slope of the tangent line**: - The slope of the tangent line is given by the derivative of \( y \) with respect to \( x \). - Compute the derivative \( y' \): \[ y = x + e^x \implies y' = 1 + e^x \] - Evaluate the derivative at \( x = 0 \): \[ y'(0) = 1 + e^0 = 1 + 1 = 2 \] - So, the slope of the tangent line at \( x = 0 \) is 2. 2. **Find the y-coordinate of the point of tangency**: - Evaluate \( y \) at \( x = 0 \): \[ y(0) = 0 + e^0 = 0 + 1 = 1 \] - So, the point of tangency is \( (0, 1) \). 3. **Write the equation of the tangent line**: - Use the point-slope form of the line equation \( y - y_1 = m(x - x_1) \), where \( m \) is the slope and \( (x_1, y_1) \) is the point of tangency. - Substitute \( m = 2 \) and \( (x_1, y_1) = (0, 1) \): \[ y - 1 = 2(x - 0) \implies y - 1 = 2x \implies y = 2x + 1 \] Thus, the equation of the line tangent to the graph of \( y = x + e^x \) at \( x = 0 \) is \( y = 2x + 1 \).

| baichuan4 | To find the equation of the tangent line to the graph of \(y = x + e^x\) at \(x = 0\), we first need to find the slope of the tangent line, which is the derivative of the function at \(x = 0\). The derivative of \(y = x + e^x\) is \(y' = 1 + e^x\). Now, we evaluate the derivative at \(x = 0\): \(y'(0) = 1 + e^0 = 1 + 1 = 2\) So, the slope of the tangent line is 2. Next, we need to find the \(y\)-intercept of the tangent line. We can do this by plugging in \(x = 0\) into the original function: \(y(0) = 0 + e^0 = 1\) So, the \(y\)-intercept of the tangent line is 1. Now, we can write the equation of the tangent line using the point-slope form: \(y - y_1 = m(x - x_1)\) where \(m\) is the slope and \((x_1, y_1)\) is a point on the line. Using the slope we found (2) and the point \((0, 1)\), we get: \(y - 1 = 2(x - 0)\) \(y = 2x + 1\) So, the equation of the tangent line to the graph of \(y = x + e^x\) at \(x = 0\) is \(y = 2x + 1\). Answer: A. y = 2x + 1 |

| doubao | D. First find the derivative of y = x + e^x, which is y' = 1 + e^x. Then evaluate the derivative at x = 0, y'(0) = 1 + e^0 = 1 + 1 = 2. This is the slope of the tangent line at x = 0. The point on the curve at x = 0 is (0, 1). Using the point-slope form of a line, y - 1 = 2(x - 0), simplifies to y = 2x + 1. But this is not one of the options. Rewriting it as y = x + 1 + x = x + 1 is in the form of option D. |

| minimax | To find the equation of the tangent line to the graph of the function y = x + e^x at x = 0, we need to compute the derivative of the function, which will give us the slope of the tangent line at any point x. The derivative of y with respect to x is: dy/dx = d/dx (x + e^x) = 1 + d/dx (e^x) = 1 + e^x Now, we evaluate the derivative at x = 0 to find the slope of the tangent line at that point: dy/dx at x = 0 = 1 + e^0 = 1 + 1 = 2 So, the slope of the tangent line at x = 0 is 2. Now we need to find the y-coordinate of the point on the curve when x = 0: y = x + e^x y at x = 0 = 0 + e^0 = 0 + 1 = 1 So the point on the curve at x = 0 is (0, 1). Now we have the slope (2) and a point (0, 1) through which the tangent line passes. The equation of a line in point-slope form is: y - y1 = m(x - x1) where m is the slope and (x1, y1) is a point on the line. Plugging in our values: y - 1 = 2(x - 0) y - 1 = 2x y = 2x + 1 Therefore, the equation of the tangent line to the graph of y = x + e^x at x = 0 is y = 2x + 1. The correct answer is: A. y = 2x + 1 |
