Answer:
- f(3) = 4
- x = -3 for f(x) = 3
Step-by-step explanation:
a) Find 3 on the x-axis. Locate the point on the graph where the vertical line x=3 intersects it. Find the y-coordinate of that point.
The point of intersection is (3, 4). Then f(3) = 4.

b) Find 3 on the y-axis. Locate the point on the graph where the horizontal line y=3 intersects it. Find the x-coordinate of that point.
The point of intersection is (-3, 3). Then f(-3) = 3; x = -3.
