Functions

Quiz Lesson:

A function is a relation with a property that for each element in the domain there is only one corresponding element in the range. Therefore all functions are relations but not all relations are functions. To identify a function we use vertical line test, if the vertical line cuts the graph more than once, then that is not a function but if it cuts only at one point, then it is a function.
