Answer:

Step-by-step explanation:
Given
The attached graph
Required
Determine the range of the graph
First, we list out the coordinate of each point on the graph:
The points are:

A function has the form: (x,y)
Where
y = range:
From the coordinate points above,

Order from least to greatest"

Hence, the range are: 
Answer:
1. 63.1. 2.22.5 3. 74.3 4. 56.1
Step-by-step explanation:
1. x: (-12, -13) y: (12, 13)
2. x: (4 ,9) y: (-4, -9)
3. x: (-10, 8) y: (10, -8)
Answer:
Yes
Step-by-step explanation:
x: -2 y: -8
x: -1 y: -2
x:0 y:0
x: 1 y: -2
x: 2 y : -8
