$f(x)=3^{x}$

#### Work Step by Step

We first find the graph of $f(x)=3^{x}$ among the graphs given from 19 to 24. The graph of $f(x)=3^{x}$ is - always above the x-axis, (graphs 20, 22, 24) - from left to right, always rises and passes through (0,1) and (1,3) Thus, the graph of $f(x)=3^{x}$ is graph 22 (this graph). $f(x)=3^{x}$
