Question

4. Select the correct equation for the resulting function.

Answer 1

Answer:

B

Step-by-step explanation:

Given f(x) then f(x + a) represents a horizontal translation of f(x)

• If a > 0 then a shift to the left of a units

• If a < 0 then a shift to the right of a units

Here the shift is - 8, thus $\sqrt{x+8}$

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

• If c > 0 then a shift up of c units

• if c < 0 then a shift down of c units

Here the shift is - 3 , thus

f(x) = $\sqrt{x+8}$ - 3 → B
