PLS HELP‼️‼️‼️

Given g(x) = 3x + 9, what function h(x) would represent a rightward shift by four units?
A)
h(x) = 3x + 5
h(x) = 3x + 13
h(x) = 3x - 5
D
h(x) = 3x - 3

Answer 1

D

Explanation:

given a function f(x) then

f(x) + c represents a vertical translation of \left[\begin{array}{ccc}0\\c\\\end{array}\right]

• If c > 0 then upward shift of c units

• If c < 0 then downward shift of c units

here g(x) is shifted down by 2 units ⇒ c = - 2

h(x) = 3x - 3 - 2 = 3x - 5 → D
