Question

Part A: Write the domain of f in interval notation.

Part B: Write the range of f in interval notation.

Part C: Find f(-4)

Part D: Find f(-2)

Part E: Find f(2)

Part F: Find the zeros of the function (the x values that make f(x)=0). If you have more than one answer, separate them with a comma.

Part G:

Find all the x -values that make the function positive (f(x)>0 when x=?). Enter your answer in interval notation. Enter −∞ as -INF, ∞ as INF, and ∪ (union) as U.

Enter the values of x from smallest to largest.

Part H:

Find all the x -values that make the function negative (f(x)<0 when x=?) . Enter your answer in interval notation. Enter −∞ as -INF, ∞ as INF, and ∪ (union) as U.

Enter the values of x from smallest to largest.

Part I: Find all y -intercepts of the function and list them as ordered pairs. If you have more than one answer, separate them with a comma.

Part J: Find all x -intercepts of the function and list them as ordered pairs. If you have more than one answer, separate them with a comma.

Given the graph of the function $ f $, find the following:

**Graph Description:**

The graph depicts a continuous curve that is plotted on a Cartesian plane. It resembles a sinusoidal curve, starting at a point around $ x = -4 $, descending to a local minimum near $ y = -3 $ at $ x \approx -2 $, then rising to cross the x-axis at the origin. From there, it peaks at a local maximum close to $ y = 3 $ around $ x = 2 $, before descending again to cross the x-axis near $ x = 4 $. The graph is highlighted in red and key points are marked with red dots.

**Axes Details:**

- The x-axis ranges from $-8$ to $8$.
- The y-axis ranges from $-3$ to $3$.

**Instructions:**

Write the domain of $ f $ in interval notation. Enter $-\infty$ as -INF, $\infty$ as INF, and $\cup$ (union) as U.
