Question

1. what is the domain of the radical function shown in the graph?the domain is $d: \\{x \leq 4\\}$.the domain is $d: \\{x \geq 4\\}$.the domain is $0, \infty)$the domain is $(-\infty, 0$

Explanation:

Step1: Identify domain from graph

The graph extends left infinitely and stops at x=4 (closed dot, so included).

Step2: Write domain in set notation

Domain: $D: \{x \leq 4\}$

Answer:

The domain is D : {x ≤ 4}.
