    end behavior => consider the highest power, if

    the power is odd and coefficient + => right up,left down

    the power is odd and coefficient - => right down,left up

    the power is even and coefficient + => right up,left up

    the power is even and coefficient - => right down,left down

    .......................................................................................................

    y = -(x-1)^2(x+3)(x-3)

    => highest power = -x^4

    the power is even and coefficient - => right down,left down
