For each of the following graphs below, write down if it is a function or not. (Function/not a Function)

no,no,no,yes

Step-by-step explanation:

If it is a function it can never over lap.  Take a piece of paper and try to move it across the line and if it ever overlaps it is not a function

1,2,3 not functions, 4 is

Step-by-step explanation:

Use the vertical line test... can you draw a vertical line through the graph and only hit 1 point- if so, it is a function- if no it isn't

Graphs 1, and 2 both have places where I would hit two points- so no

graph 3 is a vertical line- so it isn't a function either

graph 4 passes the vertical line test so it is

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
