A function in which each element of the domain pairs to exactly one unique element of the range is called a(n) _____ function.
one-to-one
A function in which each element of the range corresponds to an element of the domain is called a(n) ______ function.
onto
A relation in which the domain is a set of individual points is said to be a ___________ relation
discrete
When the domain of a relation has an infinite number of elements and the relation can be graphed with a line or a smooth curve, the relation is a _______ relation.
continuous
The test you can use on a graph to determine whether the relation is a function is called the _________ ________ test.
vertical line
The variable, often x, with values making up the domain is called the _____ variable.
