Question

What is the effect on the graph of the function f(x)=x^2 when f(x) is changed to f(x+8)?

A. Shifted up

B. Shifted left

C. Shifted right

D. Shifted down

Answer 1

f(x+8)

• (x+8)²

So

x² is changed to (x+8)²

Change in x

It will shift 8 units left

Option B

Answer 2

• B. Shifted left

Explanation:

Initial function is

• f(x) = x²

Changed function is

• f(x + 8)

This is best explained when graphed. See below to confirm the correct option
