Question

Those two questions are together. I’m confused about the domain part mostly in the first question.

Answer 1

Given:

Get 18 miles per gallon of gasoline

The tank holds 15 gallons of gasoline.

Find-: Reasonable domain and range.

Sol:

If the tank is empty

Then distance = 0

IF the tank is full

Then distance is:

`\begin{gathered} =18*15 \\ =270\text{ miles} \end{gathered}`

For domain

`(0\text{ to 15 gallons\rparen}`

So, the range is:

`\text{ Domain : }(0\text{ to }270\text{ miles \rparen}`
