The function f(x)=2x-8 is shifted 3 units up. Which equation correctly describes the new function?

Question

A. g(x)=2x-11
B. g(x)=2(x+3)-8
C. g(x)=6x-24
D. g(x)=2x-5

Answer 1

The correct choice is:

A. g(x)=2x-11

Adding 3 units up corresponds to adding +3 to the constant term in the original function.
