Question

Write the range and domain of (-4, -1) using interval notation.

A. Domain: \((-4, -1)\), Range: \((-1, -4)\)
B. Domain: \((-4, -1)\), Range: \((-4, -1)\)
C. Domain: \([-4, -1]\), Range: \([-1, -4]\)
D. Domain: \([-4, -1]\), Range: \([-4, -1]\)

Answer 1

The domain is [-4, -1] and the range is [-4, -1].

Step-by-step explanation:

The correct answer is D. Domain: [-4, -1], Range: [-4, -1].

The domain represents the set of all possible input values, while the range represents the set of all possible output values. In interval notation, a closed interval is denoted by square brackets [ ] and an open interval is denoted by parentheses ( ).

For the domain, the interval is [-4, -1]. Since the interval is closed, we use square brackets.

For the range, the interval is also [-4, -1]. Since the interval is closed, we use square brackets.
