You can check out functions here: http://www-math.mit.edu/~djk/calculus_beginners/chapter03/section01.html

Answer 6

The simplest definition is: a function is a bunch of ordered pairs of things (in our case the things will be numbers, but they can be otherwise), with the property that the first members of the pairs are all different from one another.

Answer 7

i think its option 1?

Answer 8

Essentially functions can not have multiple y values for 1 x value

Answer 9

Meaning you can't have these sort of coordinates
(4,0) (4,2) (4, -3)

because you have 3 different y values for 1 x value (4)

Answer 10

So using that, which one do you think it is?

Answer 11

4?

Answer 12

Try again, remember you can't have more than 1 y value assigned to the same x value
