What is the domain of f(x)
A: -2 < x _< 3
B: -2 _< x < 3
C: -1 < y _< 3
D: -1 _< y < 3

Answer 1

1st option: -2 < x ≤ 3

Explanation:

Domain is the set of x-values that can be inputted into function f(x).

We see that our x-values span from -2 to 3. Since -2 is an open dot, we cannot include it in our domain:

(-2, 3] or -2 < x ≤ 3
