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? −5 −1 1 5

Answer 1

the actual answer is -5

Explanation:

i just took the test and i know that even though ur numbers with the x looks like multiply but they r really squared

Answer 2

f(x) = 2x + 4

f(x-5) shifts (fx) five units to the right, then

f(x-5) = 2(x-5) + 4 = 2x - k

2x - 10 + 4 = 2x - k

k = 6
