Determine the domain for the graph below.

Question

1. -2 > x < 3
2. -2 < x < 3
3. -2 < x < 3
4. -2 < x < -3

Answer 1

3rd choice

-2 < x < 3

x is in the interval [-2, 3)

[ means include the left end point

) means do not include the right end point

the point (-5,3) has an open dot to indicate the graph does not include that point

the point (-2,0) has a dark dot to indicate the graph does include that point
