Tell whether each of the following is a function. 1. Which of the following could be a function? Select three that apply.
A {(2,5),(4, -3), (-2,1),(1,6)}
B {(1,3), (2, 1), (3,5), (1, -3)}
C {(-1, 1), (0,0), (1, 1), (-2,2)}
D {(0,0), (2,4), (2,-4), (3,9)}
E {(-2,8),(-3,-27),(-1,1),(3,27)}

A, C, E

Step-by-step explanation:

A function cannot have an x-value that produces more than y-value.  Examples would be {(2, 2), (2,3)} and {(1,0), (1,5)}.

A - This could be a function because it follows the above rule.

B - This can not be a function because it has an x-value that has two y-values.

C - This could be a function because it follows the rule.

D - This can not be a function because it has an x-value that has two y-values.

E - This could be a function because it follows the rule.

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
