Is the relation {(3, 5), (-4, 5), (-5, 0), (1, 1), (4, 0)} a function? Explain. Type your answer below.

please only answer if you're gonna explain how you got it

Respuesta :

It is a function because none of the x values repeat a number.

(3,-4,-5,1,4) 

Now if there was a repeating number for the x values such as (3,-4,-5,3,4) then it would not be a function.

Hope this Helps!!
Alright, so first make yourself a T-Chart:

X Y
-5 0
-4 5
1 1
3 5
4 0

And take a look at all the values of X and Y 

Because X does not repeat itself, it is a function

Y can repeat itself, but X cannot

I hope this helps!
