Note how the function is randomly generated, as well as the answer. Note that sampling is also available for evaluating answers. Sampling is a good alternative when students may give several equivalent forms that are difficult to compare in text. Clicking the help box next to the \textbf{Sample Points} field describes how to use sample points instead of a text comparison.
