Question

Choose 3 points as inputs to plug into the equation and show your work to find the output. y=x^2 -1

Answer 1

(0,-1), (1,0), (2,3)

Explanation:

The input values are your x values.

The output values are your y values.

So, we are going to plug in x to get y.

1. Let's plug in 0 for x.

`y=0^(2) -1`

`y=0-1`

`y=-1`

Our first point is located at (0,-1)

2. Let's plug in 1 for x.

`y=1^(2) -1`

`y=1-1`

`y=0`

Our second point is located at (1,0)

3. Let's plug in 2 for x.

`y=2^(2) -1`

`y=4-1`

`y=3`

Our third point is located at (2,3)

All done! Hope you got a better example from my explanation!
