Question

HAAALLPPP!!

Given g(x) = 5x – 3, what function h(x) would represent a upward shift by four units?

h(x)=?

Answer 1

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
