# Tell whether the function represents exponential growth or decay. k(x)=22(0.15)^x

Exponential growth and decay
Tell whether the function represents exponential growth or decay. $$\displaystyle{k}{\left({x}\right)}={22}{\left({0.15}\right)}^{{x}}$$

The given function is: $$\displaystyle{k}{\left({x}\right)}={22}{\left({0.15}\right)}^{{x}}$$
Is in the form: $$y=a(b)^x$$
