Answer
$ 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}$
