Chapter 9.9, Problem 19PPS

To determine

To calculate: To graph the function

Explanation of Solution

Given information: Function is $y=2^x+2$

Calculation:

Function is given as

  $y=2^x+2$

When $x=0$

  $y=2^0+2=1+2=3$

When $x=1$

  $y=2^1+2=2+2=4$

When $x=-1$

  $y=2^{-1}+2=\frac{1}{2}+2=\frac{5}{2}$

When $x=2$

  $y=2^2+2=4+2=6$

When $x=-2$

  $y=2^{-2}+2=\frac{1}{4}+2=\frac{9}{4}$

Function table is

x	y
-2	$\frac{9}{4}$
1	$\frac{5}{2}$
0	3
1	4
2	6

Plotting the points on graph:

  

Conclusion:

Hence, graph is plotted
