Outline Functions Representing Functions The Domain and Range Evaluating Functions Average Rate of Change The Definition of a Function Definition Suppose X and Y are sets. A function from X to Y is a rule that assigns to each x in X exactly one element y in Y . A function is a special type of relation between sets. We denote a function from X to Y by f : X Y , where f is the name of the function. The set X is called the domain of f . We call Y the target set of f . We write y = f ( x ) for the assignment of x X to y Y The element y = f ( x ) is called the function value at x .

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
