3-121.

Investigate the function $y = 2 · 4^{x}$ . What would be the effect of replacing the $2$ with a $5$? What would be the effect of adding $+1$ to the end of the equation, making it $y = 2 · 4^{x} + 1$? Include sketches as a part of your investigation.

Experiment with the functions. Creating a table of values and graph for every function will help you.
