Answers:

  • Function? Yes
  • Domain = {1, 5, 10, 11, 14}
  • Range = {6, 50, 150, 176, 256}

=============================================

Step-by-step explanation:

x = width

y = area

x is the input while y is the output.

We have a function because each input leads to exactly one output only. We don't have repeated x values.

The domain is the set of possible inputs. So we simply list the set of x values given in the table to get the domain to be {1,5,10,11,14}

The range is a similar story, but we list the possible y outputs getting {6,50,150,176,256}.

The curly braces indicate we have a set of values.
