Desmos — A quick review

When desmos plotted a line from the equation of a line given in the slope intercept form
Desmos plotting a parabola
Desmos plotting a parabola with its vertex at 4
This plot and the immediate next one is what I liked the best about Desmos. The polynomial tried out has roots 1 and -3. From the graphical representation, it can be clearly made out that the multitude of the factor 1 is in even powers and the multitude of the factor -3 has an odd power. (At point 1, we clearly have a bounce at the x axis and at point -3, we have the line crossing the x — axis)
This plot has the expanded form of the polynomial tried out in the scenario above. So, in cases like this, where the polynomial is not in the factored form, desmos can be used to find the roots of a polynomial. In this case, it looks like, we can easily make out that roots are -3 (one time or with multitude 1) and 2 with multitude 2 (cannot be more than 2, because the original polynomial has a degree of 3)
And, one last plot with Desmos. It shows the factors 2, -2 and 0. All with even multitude.
