Question

Is the answer a, b, c, or d.

Answer 1

The correct answer is D.

$-2 \leq y\ \textless \ 3$

The graph shows the set of values that y takes, so you can see that the thick black line goes from -2 to 3 and the black point at -2 represents a closed interval at this point and the empty point at 3 represents an open interval at that point.
