The graph in plane A is of the equation $x=2^y$.
Match the color of each graph in plane B with the equation that fits it. Use the fact that each graph in B can be obtained from the original by applying just one of the basic transformations which we have learned.


Important!! You only have 3 attempts to get this problem right!

1. $x=2^y-2$
2. $x=2^{-y}$
3. $x=2^{5y}$
4. $x=-2^y$

A. yellow
B. blue
