Question

Please hurry and no links, thank you!

Functions f(x) and g(x) are shown:

f(x) = x2
g(x) = x2 − 8x + 16

In which direction and by how many units should f(x) be shifted to match g(x)?

Left by 4 units
Right by 4 units
Left by 8 units
Right by 8 units

Answer 1

The answer is A. Left by four units. I took the test so it is correct, here is photographic proof:

Answer 2

it needs to be shifted to the positive side of the graph by 4 units so right by 4 units is the correct answer
