How would you get the answer for y=x^2

Question

this is a question to do with graphing quadracic equation i need details on how to solve y=x^2

Answer 1

x² functions tend to look like a U-shape. What you are doing is essentially taking your x inputs, and multiplying it by itself:

1 * 1 = 1

2 * 2 = 4

3 * 3 = 9

4 * 4 = 16

5 * 5 = 25

6 * 6 = 36

 

And so on. The same hold true when you input negative numbers because, remember, a negative times a negative equals a positive. (Imagin this. You are facing north, then you turn around to face south (one negative). Then you start jumping backwards (the second negative). You are still moving North):

 

-1 * -1 = 1
-2 * -2 = 4
-3 * -3 = 9
-4 * -4 = 16
-5 * -5 = 25
-6 * -6 = 36

 

I hope this helps you understand how a quadratic function works.
