Question

What is the range of the function `f(x) = 5 - 8x`?

Answer 1

See a solution process below:

Explanation:

First, 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}`

Here's a graph of the function for you to see that domain is `RR`.
