Question

Which best describes the range of the function f(x) = { 0)* after it has been reflected over the x-axis?

all real numbers
all real numbers less than 0
all real numbers greater than 0
all real numbers less than or equal to 0

Answer 1

all real numbers less than 0

Explanation:

In the picture attached, the question is shown.

The function described is an exponential decay with the form:

y = ab^x

where a = 2 and b = 1/4

The range of an exponential decay function is all real numbers greater than 0. This means that after f(x) has been reflected over the x-axis its range is all real numbers less than 0.
