Question

The points on the graphs represent relatons. Classify these relations according to whether or not they are functions​

Answer 1

Explanation:

A relation where each element in the domain corresponds to exactly one element in the range. If any vertical line intersects the graph more than once, then the graph does not represent a function. The notation f(x)=y, which reads “f of x is equal to y.” Given a function, y and f(x) can be used interchangeably.
