Using the graph, what is the value for the RANGE when the DOMAIN is -3?
A)
-3
B)
-1
C)
0
D)
1

Answer 1

please help me

Answer 2

domain = set of inputs

so mark x = -3 on the x axis and draw a vertical line (shown in green) through that number on the x axis. Plot the point of intersection between the green vertical line and the function curve in blue.

Now ask yourself this: "What is the y coordinate of that new blue point?"

Answer 3

so the question is basically asking you what is y when x =3
domain=x
range=y

-1, B thanks
