Hi I need help with my math problem. It is:
Name the function rule from the table given.
Table-
X= Y=
-4 4
-2 2
0 0
answers:

y = -x
y = -4
y = 2x
y = x
I do not get how to solve this problem!

    look at the first entry in the table
    if x = - 4, y = 4

    now look at each rule
    1st rule says,
    that y = -x ( y equals the neg of x)

    2nd rule says,
    y = -4 (the value for y is -4)

    3rd rule says
    y = 2x (y is two times the value of x)

    4th rule
    y = x (y and x are the same)

    since if x = - 4, y = 4 (1st entry)
    the rule would be
    y = -x

    do you understand?

    look at the other entries in the table and see how they all follow this rule
