Functions: Graphing Functions Practice MCQ

Question Statement:

$f (x) = x^{2} + 6$

Which function represents $f (x)$ being shifted to the left 4 units?

g (x) = (x + 4)^{2} - 6

g (x) = x^{2} + 10

g (x) = (x - 4)^{2} + 6

g (x) = (x + 4)^{2} + 6

g (x) = x^{2} + 2

Explanation:

Correct Answer: D

The parent function for a parabolic function is $f (x) = a (x - h)^{2} + k$ where $(h, k)$ is the center of the parabola. To shift the parabola left of right, the value of h changes. Since there is a negative sign in the parent function, a positive value moves the parabola to the left and a negative value moves it to the right.
