Now that we understand the basic shape of an exponentialfunction we can transform it using the same rules we learnedin earlier units.
The rules of: y=af(b(xh))+k also apply to:
y=a(c)b(xh)+k. The same shifts and stretches apply.
Create a chart to find the new points and then sketch.

Looking at exponential models to answer questions.
In questions b) and c) you must decide if you aresolving for X or for Y before you decide how to use your calculator!

Notice how this question is differentin 2 ways:1) The information is in % (Therefore
the number 100 is a percentage,not a value).
