Question

For which pair of functions is the vertex of g(x) 11 units above the vertex of f(x)?

Answer 1

The correct answer to the question is C

Answer 2

Answer:

C

Step-by-step explanation:

Given f(x) then f(x) + c is a vertical translation of f(x)

• If c > 0 then a vertical shift up of c units

• If c < 0 then a vertical shift down of c units

Here g(x) is 11 units above, that is a shift up, thus

g(x) = f(x) + 11, that is

g(x) = x² + 11 → C
