$ G(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) The graph of $ f(x)=3^{x}$ is graph 22. This graph (graph $24$) is obtained from the graph of $ f(x)=3^{x}$ by reflecting it about the y-axis: $ f(-x)=3^{-x}$ $ G(x)=3^{-x}$
