extreme f(xy)=x^2+2y^2-xy+14y extreme points

f (x y) = x^{2} + 2 y^{2} - x y + 14 y

extreme (x+1)/(x^2-7x-8)extreme points

\frac{x + 1}{x ^{2} - 7 x - 8}

extreme f(x)=x^3-12x^2+45x+4 extreme points

f (x) = x^{3} - 12 x^{2} + 45 x + 4

extreme f(x)=x^3-12x^2+45x+6 extreme points

f (x) = x^{3} - 12 x^{2} + 45 x + 6
