Question

find the domain & range of the given graph.
4)

Explanation:

Step1: Identify domain (x-values)

The graph extends infinitely left (towards $-\infty$) and infinitely right (towards $+\infty$), so all real x-values are included.

Step2: Identify range (y-values)

The graph extends infinitely up (towards $+\infty$) and infinitely down (towards $-\infty$), so all real y-values are included.

Answer:

Domain: All real numbers ($(-\infty, \infty)$)
Range: All real numbers ($(-\infty, \infty)$)
