Question

What is the domain and range of `f (x) = -2x + 6`?

Answer 1

See a solution process below:

Explanation:

Because there are no restrictions on the value `x` can be, then the domain of the function is the set of Real numbers: `{RR}`

The function is a linear transformation of `x` and therefore the domain is also the set of Real numbers: `{RR}`
