Please help with this

A). Not a function

B). Function

C). Function

Step-by-step explanation:

A). Since x = 3 produces y = 4 and y = 8 , the relation ( 3,4 ) , ( 3,8 ) , ( 5,7 ) is not a function.

B). Since there is one value of y for every value of x in ( 3,4 ) , ( 3,4 ) , ( 1 ,− 2 ) , this relation is a function.

C). Since there is one value of y for every value of x in ( 2,3 ) , ( 1,3 ) , ( − 5,3 ) , this relation is a function.

step-by-step explanation:

8^1/3=2

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|
