Question

Which function is an example of exponential growth?

A a(x) = 0.5(1.2)x
B b(x) = 2.4(0.86)x

Answer 1

A

Explanation:

I think you mean

A a(x) = 0.5(1.2)^x

B b(x) = 2.4(0.86)^x

an exponent to a base larger than 1 will make the function result grow exponentially (getting bigger and much bigger with growing x).

an exponent to a base between 0 and 1 will make the function result shrink and shrink dramatically with growing x.
