Question

Determine whether each relation is a function. Write yes or no.

Step-by-Step Solution

Answer

Yes, the given relation is a function.

Step 1 – Definition of function.

A relation is a function if each element of the domain is paired with exactly one element of the range.

A relation is not a function if there exist an element in the domain paired with more than one element of the range.

Step 2 – Given information.

The given table of values of a relation is:

Step 3 – Check whether the relation is function or not.

The set notation of the given relation is $\left\{\left(5,-2\right),\left(10,-2\right),\left(15,-2\right),\left(20,-2\right)\right\}$.

In this relation $5, 10, 15, 20$ all are paired with $-2$. Since each element of the domain is paired with exactly one element of the range, therefore the given relation is a function.

 Thus, the required answer is yes because the given relation is a function.
