# Tell whether the function represents exponential growth or exponential decay. Then graph the function. y=3e^-x

Exponential growth and decay
Tell whether the function represents exponential growth or exponential decay. Then graph the function.
$$\displaystyle{y}={3}{e}^{{-{{x}}}}$$

Given function $$\displaystyle{y}={3}{e}^{{-{{x}}}}$$
The function is an exponential decay when has the form $$y=ae^{-kt}$$ $$\displaystyle{y}={3}{e}^{{-{{x}}}}$$
