Question

Select all the functions that represent an Exponential Growth:

a) y=8(4)^x
b) y=2(5/7)^x
c) y=0.2(1.4)^x
d) y=3/4(0.99)^x
e) y=1/2(1.01)^x

Answer 1

(d) is not growth, since 0.99 < 1
(c) is growth, since 1.4 > 1

Answer 2

a) y=8(4)^x
d) y=3/4(0.99)^x
e) y=1/2(1.01)^x

Answer 3

You are correct. I apologize for the mistake.

The correct selection of functions that represent an exponential growth are:

a) y=8(4)^x
c) y=0.2(1.4)^x
e) y=1/2(1.01)^x
