Question

Identify the domain of the function shown in the graph.

A. -2 ≤ x ≤ 2
B. {-2,2}
C. x is all real numbers.
D. x > -2​

Answer 1

C. x is all real numbers

Explanation:

Think of domain as how far the graph expands on the x-axis as asymptotes as the limits. So in this case, the graph extends infinitely on the x-axis; so it should be all real numbers.
