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()

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
