**This is easy -- it's just a list of steps. At this level, the problems are pretty simple.**

**Let's just do one, then I'll write out the list of steps for you.**

Find the inverse of |

**STEP 1: Stick a "y" in for the "f(x)" guy:**

**STEP 2: Switch the x and y ( because every (x, y) has a (y, x) partner! ):**

**STEP 3: Solve for y:**

STEP 4: Stick in the inverse notation, |
