Answer
The graph is shown below:
Work Step by Step
Consider the functions $g\left( x \right)={{2}^{-x}}$ and $f\left( x \right)={{2}^{x}}$
Use the following steps to obtain the solution.
Step 1:
Press the [Y=] key.
Step 2:
Enter ${{\text{Y}}_{\text{1}}}={{2}^{-x}}$ and ${{\text{Y}}_{2}}={{2}^{x}}$.
Step 3:
Press the [ZOOM] key and then press [6] for standard.
Step 4:
Press the [TRACE] or [GRAPH] key to plot the graph.
g(x) is the mirror image of f(x) about the y-axis.
The x-axis is an asymptote to the function.
