Question

The graph of a function f(x) is shown below:

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

first you would find your domain which is your x the you find your range which is the y then you get the answer -2 <x_<3 which in your case is option A.

Answer 2

the domain is ur x values....so going along the line on ur x axis.....open circle means no equal sign....closed circle means there is an equal sign...
-2 < x < = 3
