CPM Homework Help : CCA2 Problem 5-89

Graph the two functions below on the same set of axes.
$y=3(2^x)\\y=3(2^x)+10$

Answer:

2 increasing exponential curves, top has asymptote at, y, = 10, graph above the asymptote, passing through the point (0, comma 13). Bottom has asymptote at, x axis, graph above the x axis, passing through the point (0, comma 3).

How do the two graphs compare?
Hint (a):
Look at their y-intercepts.
Answer (a):
The second graph is the first, but shifted $10$ units upward.
Suppose the first equation is $y=km^x$ and the graph is shifted up $b$ units. What is the new equation?
Hint (b):
See part (a).
