Chapter 9.9, Problem 22PPS

To determine

To calculate: To graph the function

Explanation of Solution

Given information: Function is $y=2^x-1$

Calculation:

Function is given as

  $y=2^x-1$

When $x=0$

  $y=2^0-1=1-1=0$

When $x=1$

  $y=2^1-1=2-1=1$

When $x=-1$

  $y=2^{-1}-1=\frac{1}{2}-1=-\frac{1}{2}$

When $x=2$

  $y=2^2-1=4-1=3$

When $x=-2$

  $y=2^{-2}-1=\frac{1}{4}-1=-\frac{3}{4}$

Function table is

x	y
-2	$-\frac{3}{4}$
1	$-\frac{1}{2}$
0	0
1	1
2	3

Plotting the points on graph:

  

Conclusion:

Hence, graph is plotted
