Question

The owner of a recreation area filled a small pond with water in 120 minutes. The pond already had some water at the beginning. What is the domain and range for this problem

Answer 1

domain is the set defined as {x: 0<=x<=120}

That is a collection of all the numbers x such that 0 <= x <= 120

`\mleft\lbrace x\colon0\le x\le120\mright\rbrace`

The range is the set given as

`\mleft\lbrace y\colon600\le y\le1500\mright\rbrace`
