Question
Exponential growth and decay
Tell whether the function represents exponential growth or decay. z(x)=47(0.55)^x

2021-01-07
The given function is: $$\displaystyle{z}{\left({x}\right)}={47}{\left({0.55}\right)}^{{x}}$$
Is in the form: $$\displaystyle{y}={a}{\left({b}\right)}^{{x}}$$
Since b=0.55
Then the function represents exponential decay.
