Question

can a relation be a function if there is a repeating number in the x-column(domain)?
(i'm just double-checking)

Answer 1

the repeating number in my x-column is -1.5 and I'm unsure if it can be a function

Answer 2

a function occurs when there's NO X-REPEATS
if there arer no x-repeast, then it's a function
otherwise, it's just a relation:)

rather

Answer 3

depends on the y value it is associated with.

Answer 4

so it isn't a function? or is it because in the y-column there are repeats as well but i thought it didn't matter on the y-column

Answer 5

a function is defined so that each x value is associated with only one y value.

if x=3, when y=7 .... then everytime x=3, it better have a y=7 associated with it.

Answer 6

if you have 2 or more values for y, when x=3 ... then its not going to be a function.

Answer 7

ohh okay that makes much more sense, thank you so much!!

Answer 8

good luck

Answer 9

just double-checking. if
x=-1.5 and y=-3.5
and for the other
x=-1.5 and y=1.5
then it is definitely NOT a function, correct?
