## Precalculus (6th Edition) Blitzer

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.
