What equation is the inverse of y=7x^2-10?

Option 2: y = ±sqrt()

Step-by-step explanation:

y = 7x^2 - 10

         To find the inverse of a function, you must swap the y and x.

x = 7y^2 - 10

         Now I will just simplify to have y by itself on the left hand side.

x + 10 = 7y^2

=y^2

sqrt()=±y

y = ±sqrt()
