To determine

To calculate: To graph the function

Answer to Problem 2GP

Graph is plotted

Explanation of Solution

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

Calculation:

Function is given as

$y=2x^2+1$

When $x=0$

$y=2{\left(0\right)}^2+1=0+1=1$

When $x=1$

$y=2{\left(1\right)}^2+1=2+1=3$

When $x=-1$

$y=2{\left(-1\right)}^2+1=2+1=3$

When $x=2$

$y=2{\left(2\right)}^2+1=8+1=9$

When $x=-2$

$y=2{\left(-2\right)}^2+1=8+1=9$

When $x=3$

$y=2{\left(3\right)}^2+1=18+1=19$

When $x=-3$

$y=2{\left(-3\right)}^2+1=18+1=19$

Function table is

x	y
-3	19
-2	9
1	3
0	0
1	3
2	9
3	19

Conclusion:

Hence, graph is plotted
