Number 2, Problem 7**
**David W. Stinson**

Try several graphs of the following function
on the same axes (i.e. use different values of *a*).

*y* = *ax*^2

I f *a
*< 0, the function is reflected over a horizontal
line. If **0 <*** a*
< 1, the function is a "stretching
out". As *a* approaches (1 ) one the function is said to be
in its parent form. As*
a* approaches (0 ) zero, the
function approaches the function *y = *0. If *a* > 1
the function is accelerating, being pulled up. As *a *approaches
positive infinity the function will approach the vertical line
of *x *= 0.
