**Test for symmetry:**
Is this graph of function symmetry w.r.t. x-Axis, y-Axis, origin or neither?

**Vertical Compressions & Stretches**
To obtain the graph of y = af(x), multiply each y-coordinate of y = f(x) by a.
Case I: |a| > 0, stretch the graph of f vertically.
Case II: 0 < |a| < 1, compress the graph of f vertically.
If a<0, the graph is reflected about the x-axis.

**Inverse of a function:**
Find the graph of an inverse function interactively. In this worksheet, students will discover the relation between the graph of a function and the graph of its inverse, and discover the relationship between the domains and ranges of each.
