Chapter 9.8, Problem 15PPS

To determine

To calculate: To graph the function

Answer to Problem 15PPS

Graph is plotted

Explanation of Solution

Given information: Function is $y=2x^2+4$

Calculation:

Function is given as

  $y=2x^2+4$

When $x=0$

  $y=2{\left(0\right)}^2+4=0+4=4$

When $x=1$

  $y=2{\left(1\right)}^2+4=2+4=6$

When $x=-1$

  $y=2{\left(-1\right)}^2+4=2+4=6$

When $x=2$

  $y=2{\left(2\right)}^2+4=8+4=12$

When $x=-2$

  $y=2{\left(-2\right)}^2+4=8+4=12$

When $x=3$

  $y=2{\left(3\right)}^2+4=18+4=22$

When $x=-3$

  $y=2{\left(-3\right)}^2+4=18+4=22$

Function table is

x	y
-3	22
-2	12
1	6
0	4
1	6
2	12
3	22

Plotting the points on graph:

  

Conclusion:

Hence, graph is plotted
