The function is linear if there is a common difference between the y-values for a constant increase in the z-values while the function is exponential if there is a common ratio between the y-values for a constant increase in the z-values.
Since there is a common ratio of 7 between the y-values for « constant increase of 1 in the x-values, then the function is exponential.
Use the exponential model $y=a{b}^{x}$
where a is the initial value (where x= 0) and & is the common ratio. Substitute a = 8 and b= 7 so: $y=8{\left(7\right)}^{x}$
or
$f\left(x\right)=8{\left(7\right)}^{x}$
