Question
Exponential growth and decay
Tell whether the function represents exponential growth or decay. f(x)=5.9(2.6)^x

2020-12-03
The given function is: $$\displaystyle{f{{\left({x}\right)}}}={6.9}{\left({2.6}\right)}^{{x}}$$
Is in the form: $$\displaystyle{y}={a}{\left({b}\right)}^{{x}}$$
Since b=2.6>1
Then the function represents exponential growth.
