come in many shapes and sizes. In fact, you’ve already
seen quadratic functions such as f(x)
= x2 + 7x –
5 in the Algebra chapter and trigonometric functions such as f(x)
= sin x and f(x)
= cos x in the Trigonometry chapter. This chapter
explains the specific notation, behavior, and properties of functions
that you will need to know for the Math IC test.
About six questions on the Math IC cover functions. These
questions can range from rather simple substitution problems to
conceptual problems about the definition of a function to questions
that test your ability to graph functions.
