    it means that you have a "parabolic" looking piece of the curve touch the x axis at 4 it doesn't cross over example |dw:1434337453732:dw|

    well if they just told you "double root at 4" there are infinitely many possibilities. There isn't enough info to determine if the "parabola" opens up or down. We also can't determine the degree or shape

    btw I'm putting "parabola" in quotes because they aren't true parabolas for polynomials of degree 3 or higher. But they look like parabolas
