Curve Derivative
1. **Problem Statement:** We need to identify which graph represents a continuous function $f$ such that $f(0) = 3$, $f'(2) = f'(-2) = 0$, and $f'(x) > 0$ for $-2 < x < 2$.
2. **Understanding the conditions:**
- $f(0) = 3$ means the function passes through the point $(0,3)$.
- $f'(2) = 0$ and $f'(-2) = 0$ mean the slope of the tangent line to the curve is zero at $x = 2$ and $x = -2$.
- $f'(x) > 0$ for $-2 < x < 2$ means the function is strictly increasing between $-2$ and $2$.
3. **Analyzing the options:**
- Graph a: Has local maxima at $x = -2$ and $x = 2$, so $f'(x)$ changes sign from positive to negative at these points, but the function is decreasing between $-2$ and $2$, which contradicts $f'(x) > 0$ there.
- Graph b: The slope is negative in some intervals between $-2$ and $2$, so $f'(x) > 0$ is not satisfied.
- Graph c: Has a local maximum at $(0,3)$, so $f'(x)$ changes from positive to negative at $0$, contradicting $f'(x) > 0$ for all $x$ in $(-2,2)$.
- Graph d: Passes through $(0,3)$, has $f'(2) = f'(-2) = 0$, and the slope is positive between $-2$ and $2$. Although it has a sharp cusp at $0$, the problem does not forbid this, and the slope condition is met.
4. **Conclusion:** Graph d satisfies all the given conditions.
**Final answer:** The correct graph is **d**.
