According to Wikipedia: "<span>In mathematics, a function
is a relation between a set of inputs and a set of permissible outputs
with the property that each input is related to exactly one output."
So based of this we need to look for a set where one of the x values or the y values is the same, and the other number is different.
Answer:
B.
(1,4) and (1,1) both have the same x, but different y!

11 x 9 is 99 so then you do 11 x d and that’s 11d so it would be 99+11d :)
I think not because a square has four sides and a triangle has three.
The function of the relationship above is y=5x+4
