# Tell whether the function represents exponential growth or decay. b(x)=13(0.7)^x

Question
Exponential growth and decay
Tell whether the function represents exponential growth or decay. b(x)=13(0.7)^x

2021-02-25
The given function is: $$\displaystyle{b}{\left({x}\right)}={13}{\left({0.7}\right)}^{{x}}$$
Is in the form: $$\displaystyle{y}={a}{\left({b}\right)}^{{x}}$$
Since b=0.7
Then the function represents exponential decay.
