Answer:

D

Explanation:

given f(x) then f(x ± a) is a horizontal translation of f(x)

• if - a , then a shift right of a units

• if + a, then a shift left of a units

the vertex of f(x) is at (0, 0 )

the vertex of g(x) is at (- 3, - 2 )

the graph of g(x) is the graph of f(x) shifted 3 units left , then

g(x) = (x + 3)² ← partial equation

given f(x) then f(x) ± c is a vertical translation of f(x)

• if - c , then a shift down of c units

• if + c, then a shift up of c units

the y- coordinates of the vertex of f(x) is shifted down by 2 units , then

g(x) = (x + 3)² - 2
