Question

The range of a relation is

A: the output (y) values of a relation
B: the input (x) values of the relation
C: a set of points that pair input values with output values
D: x and y values written in the form (x,y)

Answer 1

Consider a relation R, from M to N
that is:

R:M→N
R(x)=y

The set of all output of R,so all possible y, is called the Range of y:


Answer: A: the output (y) values of a relation
