I don't understand this question:

• Before specifying a function f(x), first determine requirements for its derivative f(x). For example, one of the requirements is that f(2)=0.
• If you want to find a function g(x) such that g(9)=0and g(8)=0, then you could try g(x)=(x+9)(x8).
• If you have a possible function forf(x), then use the techniques in Indefinite Integrals this Module to try a possiblef(x).

You can generate a plot of your function by clicking the plotting option (the page option with a "P" next to your function input). You may want to do this before clicking "How Did I Do?". Notice that the label "f(x)=" is already provided for you.

Once you are ready to check your function, click "How Did I Do?" below (unlimited attempts). Please note that the bounds on the x-axis go from -6 to 6.
