Find the Inverse of the function

Question

Find the inverse of the function:

1) f(x)=4√6x^2+12/36 (the 4 is supposed to be the root not 4 times the root if that makes sense)

2) f(x) = x+3/x-2

Answer 1

1. Im not sure what is under the radical. But try the same steps as below.

2) y = x+3/x-2

*Turn all x to y and y to x.

x = y+3/y-2

Now solve for y

x(y-2) = y+3

xy-2x = y+3 *put all y's on one side of equation*

xy-y = 2x+3

y(x-1) = 2x+3

y = 2x+3/x-1

f(x) = 2x+3/x-1
