Select Is a Function or Is not a Function to correctly classify each relation.

Step-by-step explanation:

Firs we need to understand what is a function-

from a set to a set is an assignment of an element of to each element of .

This mean's that an element in can't have multiples values in , then if you find a coordinate with two different values, isn't a function.

Take for example the second data set:

All is good except for the first two coordinates because is define with two different values, then you can determinate that isn't a function.

Maybe you're confuses because exist some graphs that repeat values in as the graph of a circle, but this in reality isn't a function, is a relation. A relation can repeat values in the set infinity times but never is going to be a function.

step-by-step explanation:

a constant is a number without a variable, and m will always have a variable, therefore making m a constant. a term is just a part of an equation, so that makes any part of an equation always a term, so the answer will not be term.
