Question

Function h is a transformation of the parent exponential function, f(x) = 2³.

h(x) = -3 • 2³.
Which statement is true?
A. Function h is a reflection and a dilation of function f.
B. Function h is a reflection and a translation of function f.
C. Function h is a horizontal translation of function f.
D. Function his a vertical translation of function f.

Answer 1

A. Function h is a reflection and a dilation of function f.

Explanation:

Reflection: The negative sign in -3 indicates that function f is a reflection over the y-axis

Dilation: The 3 indicates a dilation, specifically a vertical stretch.
