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!

    Also please do NOT tell me the answer but show me how to solve it. Thanks everybody!

    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
