Question

What is the domain and range of `y = 3x+6`?

Answer 1

`"dom: " x in RR`
`"ran: " y in RR`

Explanation:

• The domain is defined as the set of all the possible x-values that can be input into the function.
• The range is defined as the set of all the possible y-values that can be input into the function.

Linear functions generally have a domain and range of `RR` (all real values). Unless there is a restriction of the domain of the linear function, the domain and range of `y` will be `RR`.
