Find the Exponential Function (0,5)

To find an exponential function, ${\displaystyle f\left(x\right)=a^x}$, containing the point, set ${\displaystyle f\left(x\right)}$ in the function to the ${\displaystyle y}$ value ${\displaystyle 5}$ of the point, and set ${\displaystyle x}$ to the ${\displaystyle x}$ value ${\displaystyle 0}$ of the point.
