Question

For the relation $\left\{\left(1,3\right),\left(2,6\right),\left(3,9\right),\left(4,12\right),\left(5,15\right)\right\}$:

a. Find the domain of the relation.

b. Find the range of the relation.

Step-by-Step Solution

Answer

a. The domain of the relation is : $\left\{1,2,3,4,5\right\}$ .

b. The range of the relation is : $\left\{3,6,9,12,15\right\}$.

Step 1: Given data

$\left\{\left(1,3\right),\left(2,6\right),\left(3,9\right),\left(4,12\right),\left(5,15\right)\right\}$

Step 2: Definition

A relation is any set of ordered pairs, $\left(x,y\right)$. All the x-values in the ordered pairs together make up the domain.  All the y-values in the ordered pairs together make up the range.    

Step 3: Final answer

The domain of the relation is $\left\{1,2,3,4,5\right\}$ .

The range of the relation is : $\left\{3,6,9,12,15\right\}$.
