Chapter 9.9, Problem 21PPS

To determine

To calculate: To graph the function

Explanation of Solution

Given information: Function is $y=3^x+1$

Calculation:

Function is given as

  $y=3^x+1$

When $x=0$

  $y=3^0+1=1+1=2$

When $x=1$

  $y=3^1+1=3+1=4$

When $x=-1$

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

When $x=2$

  $y=3^2+1=9+1=10$

When $x=-2$

  $y=3^{-2}+1=\frac{1}{9}+1=\frac{10}{9}$

Function table is

x	y
-2	$\frac{10}{9}$
1	$\frac{4}{3}$
0	2
1	4
2	10

Plotting the points on graph:

  

Conclusion:

Hence, graph is plotted
