Basically, this is the same as the other inverse functions you’ve worked on.
1. replace the f(x) with a y
2. swap the x and y
3. solve for the new y
f(x)=3x^2-2
Inverse:
x=3y^2-2
x+2=3y^2
(x+2)/3 = y^2
Square roof of ((x+2)/3) = y
inversef(x)=Square root of ((x+2)/3)= g(x)
And then the inverse of this function is the same as the original.
