Question

Can some please teach m e how to solve this?
I got no clue how to solve it

Answer 1

Remember a function must have only one y value for each x value you put in

Answer 2

My best guess is it's A..or B

Answer 3

I agree with great life. So basically, you can't have two or more different y values for the same X.

Looking at A: One of the X values is -2. -2 has more than one y value. It has 2 and 6. Because of that, it's not a function

Answer 4

So it's B! Because it does have 2 of the same numbers, except in the y value

Answer 5

yes b

Answer 6

doesn't*

Answer 7

Right, C and D also have multiple Y-values for the same X number

Answer 8

Awesome! Thank you so much! <3 You're awesome!
