4. If a function, f(x) is shifted to the left four units, what function represents the transformation?
A. f(x-4)
B. f(x) - 4
C. f(x+4)
D. f(x) + 4

Answer 1

This is a horizontal shift so
f(x+4)
with phase shifts the inside is the opposite of it
(x-4) would be right four units
and vice versa for +4

Answer 2

C. to the left its positive right its negative
