extreme Q(x,M)=x-(((x-d))/(M/3))

extreme points

Q (x, M) = x - (\frac{( x - d )}{\frac{M}{3}})

Saddle (d, 3)

Solution steps

Find the critical points:

(d, 3)

\frac{\partial ^{2} f}{\partial x ^{2}} = - \frac{6 ( x - d )}{M ^{3}}

D (x, M) = - \frac{9}{M ^{4}}

Check the sign of at each critical point

Check critical point

(d, 3) :

Saddle

Saddle (d, 3)

\frac{10}{- X + 25}

f (x) = 2 x^{3} - 4 x^{6} + 2 x^{2}

f (x) = 5 + 2 x + 8 x^{- 1}

f (x) = \frac{x}{x ^{2} + 108}

f (x) = - 4 x^{2} + 96 x - 490
