Question

30) State the DOMAIN of the graph shown:

A] -4 ≤ y ≤ 3
B] -4 < y < 3
C] -5 ≤ x < 4
D] -5 < x≤ 4

Answer 1

Answer: C

Explanation:

The closed circle on the left denotes "or equal to," and the open circle on the right denotes "less than."

So, it cannot be A, B, or D because they do not have
`\leq` on the left and < on the right.

Only C has that option.
