Question

How do you find the domain and range of `f(x)= x-7`?

Answer 1

See a solution process below:

Explanation:

`x` can take any value without violating any rules of math.

Therefore, the domain, or input, for this function is the set of all Real numbers: `{RR}`

Because this is a linear transformation, the range, or output, for this function is also the set of all Real numbers: `{RR}`
