Question

How do you find the domain and range of `f(x)=3x-2`?

Answer 1

Domain `{x in RR }`

Range `{y in RR}`

Explanation:

This is just the equation of a straight line. The function is continuous so the domain is:

`{x in RR }`

The minimum value is `-oo`
The maximum value is `oo`

So the range is:

`{y in RR}`
