Determine whether the function represents exponential growth or exponential decay. Then graph the function. y=(0.8)^{x}

Step 1
Determine weather for the following function is represent exponential growth or exponential decay. Then graph the function:
${\displaystyle f\left(x\right)={\left(0.8\right)}^x}$
There is a general rule for the exponential function depending on the base of exponent as follows:
${\displaystyle y=b^{x}b>1\therefore \text{Represent for exponential growth function.}}$
${\displaystyle y=b^{x}0<b<1\therefore \text{Represent for exponential decay function.}}$
For this function, ${\displaystyle \because \left(0<b<1\right)}$
${\displaystyle \therefore }$ This function is represent for exponential decay function.
