Answer:
B. -5 ≤ x ≤ 5
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
We see that our x-values span from -5 to 5. Since both are closed dots, they are included in the domain:
[-5, 5] or -5 ≤ x ≤ 5
A, if continuous; c, if not
continuous is if it has arrow
x is the line across
