Answer:B, Right by 4 units

Step-by-step explanation:we want to factor g(x), and the factorization of that would be (x – 4)² as its a perfect square trinomial

when translating on a graph, we determine the translation. the translation of g(x) is a

horizontal shift 4 units to the right, as we are subtracting 4. if it was adding 4, we would be shifting to the left 4 unitsANSWER

Right by 4 units

EXPLANATION

The given functions are

and

To obtain how much f(x) is shifted to obtain g(x), we need to rewrite g(x) in vertex form.

Observe that,

is a perfect square trinomial.

The vertex form is

When f(x) is shifted 4 units to the right, we obtain g(x).
