Question

How do you find the domain and range of `f(x) = -5x +4`?

Answer 1

The Domain, or input, into the function has no constraints on the value `x` can take. Therefore, the Domain of the `f(x)` is the set of all Real Numbers or `{RR}`

This function is a straight linear transformation therefore the Range of the function is also the set of all Real Numbers or `{RR}`
