Question

Identify the domain of the function.

A) D: −2 < x < 4
B) D: −3 < x < 3
C) D: −2 ≤ x ≤ 4
D) D: −3 ≤ x ≤ 3

Answer 1

For this case the first thing you should do is observe all the values of x that the function takes along the graph.
We have then that the graph:
It starts at x = -2 (not including it)
Ends in x = 4 (not including it)
Therefore, the domain of the function is:
(-2, 4)
Answer:
A) D: x
