Step by step solution

01

Step 1. Given information.

Graph each equation by hand by plotting points. Verify your results using a graphing utility.

y=x2-1

02

Step 2. Create table of values.

Start by creating a table of values, we will then use it to plot the points on the graph. select values of x and use the given equation to find the corresponding values of y.

03

Step 3. Create the graph. 

Plot the points from the table above and connect them with a smooth curve.

04

Step 4. Conclusion.

The required graph is
