Which of the following statements is not true?
A. If the domain and range of a relation are sets of real numbers, then the relation can
be represented by plotting ordered pairs in the Cartesian plane.
B. If the domain of a function consists of more than one element, then the range must
also consist of more than one element.
C. Two or more distinct elements in the domain of a function can correspond to the
same element in the range.
D. Every function is a relation but not every relation is a function. - Answer-B. If the
domain of a function consists of more than one element, then the range must also
consist of more than one element.

corresponding element in the range.
D. A function is a relation such that for each element in the range, there is exactly one
corresponding element in the domain. - Answer-C. A function is a relation such that for
each element in the domain, there is exactly one corresponding element in the range.
