Question

The function y = (4)(1/2)^x is an example of

exponential decay

a higher order polynomial

a quadratic equation

exponential growth

The function y = (1/2)(3)^x is an example of

a higher order polynomial

exponential decay

a quadratic equation

exponential growth

Answer 1

The function y = (4)(1/2)^x is an example of

exponential decay, because the b term, 1/2<1.

The function y = (1/2)(3)^x is an example of

exponential growth, because the b term, 3>1.

Answer 2

Hi D.C L,

The function y = (4)(1/2)^x

FIRST, this function is exponential function because the power includes x

Second, if the base is less than 1 it is exponential decay

Third, The function y = (1/2)(3)^x is exponential growth because the base is greater than 1

as a result growth and decay depend on the base ; Base<1 decay

Base>1 growth

I hope it is useful,
