If g(x)=4x-6 then g^-1(x)=?
(1) -4x+6
(2)-1/4x+1/6
(3)1/4x+3/2
(4)1/4x+6

Given:

To find:

The function .

Solution:

we have,

Put g(x)=y.

Interchange x and y.

Isolate y.

Substitute .

Therefore, the correct option is (3).

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
