Change the standard form equation to vertex form and compare the function to the parent function y = x^2.

1. y = x^2 - 2x - 2

Completing the square gives

and comparing to , the graph of would be a horizontal shift to the right by 1 unit, and a vertical shift down by 3 units.

Hope this help!!!

Have a nice day!!!

i would say true? if the unit was informational and it "refreshed your understanding", then true.

substitute,

circle 1 = 5

circle 2 = 20

circle 3 = 44

in this case no matter how you add, you will always get a perfect square..

hence proved

happy to
