1. **Problem Statement:** Given the graph of the function $y = f(x)$, answer the following questions based on the graph.
2. **(a) Evaluate $f(-2)$ and $f(6)$:**
- From the graph, $f(-2) = 0$ (given).
- $f(6)$ is not explicitly given, but from the graph near $x=6$, the value is approximately $3$ (given).
3. **(b) Find $f(2) - f(-6)$:**
- From the graph, $f(2) = 3$ and $f(-6) = 8$.
- Calculate: $$f(2) - f(-6) = 3 - 8 = -5$$
4. **(c) State the zeros of the function:**
- Zeros are where $f(x) = 0$.
- From the graph, zeros occur at approximately $x=0$ and $x=4$.
5. **(d) Find the y-intercept:**
- The y-intercept is the value of $f(0)$.
- From the graph, $f(0) = 0$.
6. **(e) State the minimum and maximum values:**
- Maximum value is at $(-7, 8)$.
- Minimum value is at $(-4, -4)$ (note: graph shows minimum at $(-2, -5)$, but problem states $(-4, -4)$; assuming $(-2, -5)$ is correct from graph).
7. **(f) Coordinates of turning points:**
- Maximum at $(-7, 8)$.
- Minimum at $(-2, -5)$.
8. **(g) Interval where function is increasing:**
- From $x = -2$ to $x = 5$, the function increases (from $-5$ to $5$).
9. **(h) Over interval $-5 < x < 4$, is the function positive or negative?**
- From $x=-5$ to $x=0$, $f(x)$ is negative (below x-axis).
- From $x=0$ to $x=4$, $f(x)$ is positive (above x-axis).
- So, the function is negative for $-5 < x < 0$ and positive for $0 < x < 4$.
**Final answers:**
- $f(-2) = 0$
- $f(6) = 3$
- $f(2) - f(-6) = -5$
- Zeros at $x=0$ and $x=4$
- Y-intercept at $0$
- Maximum at $(-7, 8)$
- Minimum at $(-2, -5)$
- Increasing on interval $(-2, 5)$
- Function negative on $(-5, 0)$ and positive on $(0, 4)$
