Question

Identify the domain of the function.
A) D:{x| −2 < x < 4}
B) D:{x| −3 < x < 3}
C) D:{x| −2 ≤ x ≤ 4}
D) D:{x| −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 | -2 <x <4}
