Answers:
- Function? Yes
- Domain = {1, 5, 10, 11, 14}
- Range = {6, 50, 150, 176, 256}
=============================================
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.
