Question

find the domain & range of the given graph.
9)

Explanation:

Step1: Identify domain from graph

The graph is a vertical line at $x=6$ (all points have $x$-coordinate 6).

Step2: Identify range from graph

The line extends downward infinitely, and has an open circle at $y=15$, so $y$ is all real numbers less than 15.

Answer:

Domain: $\{6\}$
Range: $(-\infty, 15)$
