Question

Idenify the domain for the function, f(x).

(Negative infinity, infinity)
(Negative infinity, 0) Union (0, infinity)

(Negative infinity, 2) Union (0, 2) Union (0, infinity)

(negative infinity, negative 2) Union (negative 2, 0), union (0, infinity)

Answer 1

A. (negative infinity, infinity)

Explanation:

Answer 2

`Domain = (-\infty,\infty)`

Explanation:

The function is not given; So, I will answer this question using

`f(x) = 1.6x - 2`

Required

The domain

In
`f(x) = 1.6x - 2`,

- there is no fraction where x is in the denominator

- there is no root where x is in the radicand

This means that, there is no restriction on x.

Hence, the domain is:

`Domain = (-\infty,\infty)`
