Given the family of functions

with parameters **a** and **b**, determine what is the effect on the
graph when you change the values of **a** and **b**.

Using Fortune (from the University of Arizona):

- After starting up the program, you are prompted
*"Would you like some instructions?"*Use the arrow keys to move to either*Yes*or*No*and then press . - If you choose
*Yes*then read the instructions and press when you are ready to proceed. - Use the arrow keys to highlight
*Function Operations*and press . - Use the arrow keys to highlight
*Create Function*and press . - At the prompt,
*f(x) =*, typea*(x-b)^3 . - Use the arrow keys to move to
*Plot Function*and press . - You will now see the graph of the function when
*a = 1*and*b = 0*. Each time that you type uppercase the value of*a*will be increased by one and the associated function plotted. By typing lowercase you will decrease*a*by one. Similarly, each time that you type uppercase the value of*b*will be increased by one and the associated function plotted. By typing lowercase you will decrease*b*by one.
