Question

What is the domain of `f(x)=3x-1`?

Answer 1

The domain for `f(x) = 3x - 1` is all real numbers.

The domain of a function is the set of input for a function, here `f(x)`, for which the function has a value. For any real numbers you plug into `x`, the function `f(x)` will produce a value.

Examples:

`f(0) = 3(0) - 1 = 0`
`f(5) = 3(5) - 1 = 14`
`f(71) = 3(71) - 1 = 212`
