Hey, I have some questions.

How would I find the domain and range for these equations:

y = -5x^2 + 1
y = 3x^2 + 3
x = -x^2 + 5

Also, how would I solve these equations:

(2x + 2)^2 = 1
7x = 3x^2 - 1

Thanks for the help!

well to start you take they first number and divide is by pi... that's all im givin ya
