f(x)=x^2-81\\
y=x^2-81\\
x^2=y+81\\
x=\pm \sqrt{y+81}\\
f^{-1}(x)=\pm \sqrt{x+81}\\

f(x)=2x-6\\
y=2x-6\\
2x=y+6\\
x=\dfrac{1}{2}y+3\\
f^{-1}(x)=\dfrac{1}{2}x+3\\
f^{-1}(2)=\dfrac{1}{2}\cdot2+3\\
f^{-1}(2)=1+3\\
f^{-1}(2)=4

3x2 - 2x = 0<br> Factorise and solve
malfutka [58]

 Solve  :    3x-2 = 0  

Add  2  to both sides of the equation :  

                     3x = 2

Divide both sides of the equation by 3:

                    x = 2/3 = 0.667

Two solutions were found :

x = 2/3 = 0.667

x = 0

hope this helped
