Question

The graph of f(x) = 2x + 4 shifts five units to the right when it is replaced with the graph of f(x) = 2x − k. What is the value of k?

A. 5
B. −1
C. 1
D. 4

Answer 1

A

Explanation:

Answer 2

• k = 6

Explanation:

Given function:

• f(x) = 2x + 4

Shifting right 5 units:

• f(x - 5) = 2(x - 5) + 4 = 2x - 10 + 4 = 2x - 6

New function is:

• f(x) = 2x - 6

The value of k is 6

The answer choices don't include 6, it might be a typo?
