Question

Which function is decreasing and approaches negative infinity as x increases?

A. f(x) = -3(0.6)^x + 1
B. f(x) = 3(6)^x − 2
C. f(x) = -3(6)^x + 2
D. f(x) = 3(0.6)^x − 1

Answer 1

C

Explanation:

I have attached graphs of all the equations below

A starts off increasing so it cannot be it

B is increasing after some point, so doesn't work

C works

D has a constant y after some point, so doesn't work (not increasing or decreasing)

therefore: C is the correct answer
