To find the inverse of a function algebraically: 1) Change the f(x) to y 2) Switch the x and the y. 3) Solve for y. 4) Replace y with f 1 (x)

Inverse Functions

The INVERSE of a function swaps the domain (x) and range.  You can do this with a table of values, a graph, or a single point.  

To find the inverse of a function algebraically:

1) Change the f(x) to y

2) Switch the x and the y. 

3) Solve for y. 

4) Replace y with f­1(x)

To find the inverse graphically:

1) Make a table of values for the function. 

2) Make a new TOV where the domain and the range switch places. 

3) Graph
