Questions: State the domain and range and determine if it's a function? Domain: Range: Function? No

Transcript text: 11 State the domain and range and determine if it's a function? Domain: $\square$ Range: $\square$ Function? $\square$ No

Solution

Step 1: Identifying the Domain

The domain consists of all the input values, which are the elements in set $x$. These values are 3, 6, 12, and 18.

Step 2: Identifying the Range

The range consists of all the output values, which are the elements in set $y$. These values are 5, 7, 9, and 10.

Step 3: Determining if it's a Function

A relation is a function if each input value in the domain maps to exactly one output value in the range. In this case:

Since the input 6 maps to two different outputs (7 and 10), this is not a function.

Domain: $\boxed{\{3, 6, 12, 18\}}$ Range: $\boxed{\{5, 7, 9, 10\}}$ Function? $\boxed{\text{No}}$
