Work Step by Step

Find the value of\[f\left( x \right)\]for different value of\[x\], and make a table as: When \[x=-2\] \[\begin{align} & f\left( x \right)={{4}^{-2}} \\ & =\frac{1}{16} \\ & =0.0625 \end{align}\] When \[x=-1\] \[\begin{align} & f\left( x \right)={{4}^{-1}} \\ & =\frac{1}{4} \\ & =0.25 \end{align}\] When \[x=0\] \[\begin{align} & f\left( x \right)={{4}^{0}} \\ & =1 \end{align}\] When \[x=1\] \[\begin{align} & f\left( x \right)={{4}^{1}} \\ & =4 \end{align}\] When \[x=2\] \[\begin{align} & f\left( x \right)={{4}^{2}} \\ & =16 \end{align}\]
