Answer:

Please find attached the required graph of the inequality, y created using Microsoft Excel

Explanation:

The inequality is presented as follows;

y > x² + 2·x - 8

We can graph the inequality using Microsoft Excel by generating the data points as follows;

x
{} y

-9
{} 55

-8
{} 40

-7
{} 27

-6
{} 16

-5
{} 7

-4
{} 0

-3
{} -5

-2
{} -8

-1
{} -9

0
{} -8

1
{} -5

2
{} 0

3
{} 7

4
{} 16

5
{} 27

6
{} 40

7
{} 55

8
{} 72

9
{} 91

The points are plotted and a dashed line is used to join the points to represent the > inequality symbol. The region above the graph of the inequality is then shaded.

For #3, graph the inequality. 3. y > x2 + 2x -8-example-1
