Best ResponseYou've already chosen the best response.2The roots are the x intercepts. Set y to 0 and you will see that x=0 is a double root which indicates a point of tangency to the x axis at x = 0

Best ResponseYou've already chosen the best response.0\[y=x^2\]\[x^2y=0\]\[x_{1,2}=\frac{0\pm\sqrt{0^24(1)(y)}}{2(1)}\\=\frac{\pm\sqrt{4y}}{2}\\ =\pm \sqrt y\]
