Question: 191

15.

The graph shown here is of f(x) = (x - 2)2.

Which of the following choices represents the graph of y = f(x) + 3?

A.
B.
C.
D.
E.

Correct Answer: E

Explanation:

E. Adding 3 to a function adds 3 to the y-value of each coordinate on the graph. Therefore, f(x) + 3 will look like f(x) shifted vertically upwards by 3 units. Choice (E) is the only option that shows the original graph shifted upwards.
