Question

what is the domain?
-3 ≤ x ≤ 1
y ≤ 8
all real numbers

Explanation:

The domain of a graph is the set of all valid x-values the function covers. Looking at the graph, the leftmost x-intercept is at $x=-3$ and the rightmost is at $x=1$, so all x-values between and including these points are the domain. The option $y \leq 8$ refers to the range, and "All real numbers" is incorrect as the graph does not extend infinitely left/right.

Answer:

-3 ≤ x ≤ 1
