Question

What is the domain of g?

A. -7 ≤ x ≤ 7
B. The x-values -7, -2,5, and 7
C. 0 ≤ x ≤ 7
D. The x-values 0,2,4,5, and 7

Answer 1

D choice.

Explanation:

Domain is not continuous so there cannot be b < x < a.

Therefore, we can rule out A and C choice.

B choice is incorrect because -7 is not part of the domain (as shown in the graph.)

So the answer is D.
