Question

can somebody tell me how to find the inverse of a function algebraically??

Answer 1

Swap the variables. E.g., if you have\[y=3x+2,\]to find its inverse, you swap the variables\[x=3y+2,\]and solve for y.

Answer 2

\[y=\frac{x-2}{3}\]

Answer 3

replace x by y and y by x and solve for y to get the inverse
