Question

choose 1 answer: a -7 ≤ x ≤ 7 b the x - values -7, -4, 0, 4, and 7 c -3 ≤ x ≤ 4 d the x - values -3, 0, and 4

Explanation:

Step1: Identify domain concept

The domain of a function is the set of all possible x - values.

Step2: Observe the graph

The left - most x - value of the graph is \(x=-7\) and the right - most x - value is \(x = 7\). The function is defined for all x - values between and including these endpoints.

Answer:

A. \(-7\leq x\leq7\)
