Approximate the Point of Intersection of the Graphs of F $f ( x ) = g ( x )$

Short Answer

Approximate the point of intersection of the graphs of f and g. Then solve the equation $f ( x ) = g ( x )$ algebraically to verify your approximation.
​ $$\begin{array} { l } f ( x ) = 3 ^ { x } \\g ( x ) = 9\end{array}$$ ​ ​
