n: 2, 4, 6
m: -6, -12, -16

Which function rule would help you find the values in the table.


m = -3n
m = n - 6
m = n -3
m = -6n

    Please help

    Well, I'd say -3n, except that -3(6) = -18, not -16.

    Typo?

    As you can see, none of the choices fits all three pairs.

    M = - 3n?

    does that make a differnece?

    forgot to change name ☺

    m = - 3n?

    does that make a differnece?

    You can see that the three points do not lie on a straight line, so no linear function will do. There is a parabola which contains all three points

    m = (n^2-18n+8)/4

    but that's not an option

  • Math - ,

    So which one would be the best one to pick?

  • Math - ,

    NONE
    unless the -16 is really -18

    But, m = -3n is the closest of the three.

    At least it contains two of the pairs; the other choices miss the mark for all three of them.

    WAIT! It is -18 not -16. Sorry

    LOL ☺ Sorry for the trouble i now know the answer. Thanks you soo much

  • Math - ,

    i get it
