Multiple Choice

Determine whether the given function is exponential or not. If it is exponential, identify the value of the base a.
- $\begin{array}{cc}\hline \mathrm{x} & \mathrm{H}(\mathrm{x}) \\\hline-1 & \frac{5}{8} \\0 & 1 \\1 & \frac{8}{5} \\2 & \frac{64}{25} \\3 & \frac{512}{125} \\\hline\end{array}$

A) Exponential; $a = \frac { 5 } { 8 }$
B) Exponential; $a = 8$
C) Exponential; $a = \frac { 8 } { 5 }$
D) Not exponential
