CPM Homework Help : INT3 Problem 7-83

Use the graph below to solve $2^{x} + 1 < 3^{x}$ .

2 exponential curves, one with x axis as horizontal asymptote, passing through the point (0, comma 1), & other with, y = 1 as horizontal asymptote, passing through the point (0, comma 2). The curves intersect at the point (1, comma 3).

Hint:

First decide which curve represents $y = 3^{x}$ . Highlight this curve. For what values of $x$ is your highlighted curve above the other curve?

Answer:

$x>1$
