Question

Given set A = { (2, 5 ), ( 3, 6 ), ( 1, 4 ), ( -1, 0 ) }. Is the set a function. Yes or no?

Answer 1

A function assigns one and only one y-value for an x value. Is that what you're seeing here? In other words...is there any "overlap?"

Answer 2

what does a overlap mean

Answer 3

are any of these the same?

Answer 4

there is only one x value for one y value given that each set is. (x,y)

Answer 5

so given this information it is easy to see that A is a function because there is only one y value for each x value.

Answer 6

thank yu
