Answer:
D
Step-by-step explanation:
Answer:
See below.
Step-by-step explanation:
f(3) means the y-coordinate of the point that has x-coordinate 3.
To find f(3) using a graph of f(x).
Look up x = 3 on the x axis. If the function passes through that point on the x-axis, then f(3) is 0. If the function does not pass through that point, then go up or down till you intersect the function. Draw a horizontal segment left to the y-axis and read the point on the y-axis that the horizontal segment intersects. That is what f(3) is equal to.
