Functions
Functions
Functions come in many shapes and sizes. In fact, you’ve already seen quadratic functions like f(x) = x2 + 7x – 5 in the algebra chapter and trigonometric functions like f(x) = 2 sin x + cos2x in the trigonometry chapter. This chapter explains the specific notation, behavior, and properties of functions that you will need to know for the Math IIC test.
About 12 questions on the Math IIC test 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. If you find functions to be a difficult subject, you may be want to consider taking the Math IC test, which asks about half as many questions on this topic as the Math IIC does.
