Using Feb 18 (75198 confirmed) as the origin, and March 19 (233752 confirmed)
as the last point on the graph, and assuming the curve is roughly quadratic, I
get the equation of the curve to be f(x)=176x**2 +75198. That would mean that in
30 more days our confirmed cases would be roughly 708,798.

I hope my math is bad.

It should be noted that those are worldwide confirmed cases, not "our"
(meaning USA) confirmed cases.

Correct

I am struggling with this. Math was never my strong suit
and it's been a long time ...

It's not a complete quadratic equation unless I am
missing something (which is very possible).


y=x**2 is a complete quadratic equation. You're thinking of the form
y=ax**2+bx+c, in this case b=0, and c=75,198.

In my case the vertex was at the point 0,75198. So the 'b' term is 0. Written
out completely, the equation would be: f(x)=176x**2+0x +75198. That probably
looks more familiar.

Thanks. I need to go back to school.
