Question

PLEASE HELP.. Sharlene purchased a new truck, whose value over time depreciates. Sharlene's truck depreciates according to the function y = 46,638(0.78)x, where x represents the number of months since the truck was purchased. What is the range of the exponential function y based on its equation and the context of the problem?
A. y ≥ 0
B. y < 46638
C. 0 < y ≤ 46638
D. ℝ

Answer 1

Using it's concept, the range of the given exponential function is:

C. 0 < y ≤ 46638.

What is the range of a function?

The range of a function is the set that contains all possible output values for the function.

In this problem, the function is:

y = 46,638(0.78)^x.

It is an exponential function with initial value 46,638 and rate of change 0.78. Exponential functions that are not shifted down, such as this one, are never negative nor zero, hence the range also has the restriction y > 0, and is given by:

C. 0 < y ≤ 46638.
