In order to find three points on this graph, let's choose values of x and calculate the corresponding values of y.
So we have:
[tex]\begin{gathered} y=4^x \\ \\ x=0\colon \\ y=4^0=1 \\ \\ x=1\colon \\ y=4^1=4 \\ \\ x=-1\colon \\ y=4^{-1}=0.25 \end{gathered}[/tex]
Now, graphing the points (-1, 0.25), (0, 1), (1, 4) and the function, we have:
