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.
