Question

If f(x) is shifted to the left four units what function represents the equation

Answer 1

f(x +4)

Explanation:

Translation by (h, k), h units right and k units up, is accomplished by the transformation ...

f(x -h) +k

You want translation 4 units left, so you want (h, k) = (-4, 0). The shifted function is ...

f(x +4)
