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

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

Step-by-step 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.

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

2. Let's plug in 1 for x.

Our second point is located at (1,0)

3. Let's plug in 2 for x.

Our third point is located at (2,3)

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

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)  

1/4 is the asnwer cuz 5/20 is the faction
