6x^2 + 5x +7 =y

dy/dx = 12x + 5 

To solve for a point of inflection:

dy/dx = 12x + 5 = 0

x=-5/12

y=143/24

The general form of a quadratic equation is, ax² +bx + c = 0. If we divide all terms by a we get, x² +(b/a)x + c/a = 0. then by completing the square we get (x+(b/2a))² + ...

The reason Copper and Chromium have a slighly odd electron configuration is because of stability. By only having 1 electron in the 4s oribtal, Chromium is able to have 1 electron in each of it's 3d orbita...

Just because a function is continuous at a point, that doesn't mean it has a derivative at that point. If a function is differentiable on an interval, then it is continuous on that interval, but the rever...
