question\ngiven the graph of $f(x)$ below, find the graph of the derivative of $f(x)$.\nselect the correct answer below:
Answer
Explanation:
Step1: Identify the vertex of the parabola
The vertex of $f(x)$ is at $x = 0$, where the slope is zero. $$f'(0) = 0$$
Step2: Determine the sign of the derivative
For $x < 0$, $f(x)$ is decreasing, so $f'(x) < 0$. For $x > 0$, $f(x)$ is increasing, so $f'(x) > 0$. $$f'(x) < 0 \text{ for } x < 0, f'(x) > 0 \text{ for } x > 0$$
Step3: Calculate the slope of the derivative
The function $f(x)$ passes through $(0, -1)$ and $(2, 3)$. Assuming $f(x) = ax^2 + c$, then $c = -1$ and $3 = a(2)^2 - 1$, so $a = 1$. $$f(x) = x^2 - 1 \implies f'(x) = 2x$$
Step4: Match with the correct graph
The derivative $f'(x) = 2x$ is a line passing through $(0,0)$ with a positive slope of $2$. $$\text{Graph passes through } (0,0), (1,2), (2,4)$$
Answer:
The second option (the graph of a line passing through the origin $(0,0)$ with a positive slope).
