Let’s cut right to the chase on this one. If you have the function f(x)= 3x+5, this is how you find its inverse.

1. Rewrite it as y=3x+5

2. Change the y to x. Change the x to y. That gives you x=3y+5.

3. Solve this new equation for y. 3y= x-5. Then divide by 3. y=(x-5)/3. This is the inverse.

If you look at the graph of a function, you can find its inverse by reflecting (flipping) the graph over the line y=x. The resulting graph is the inverse of the original function. More about functions tomorrow.
