extreme (x^2-11x+67)/(x-9)

extreme points

\frac{x ^{2} - 11 x + 67}{x - 9}

Maximum (2, - 7), Minimum (16, 21)

Solution steps

f^{'} (x) = \frac{x ^{2} - 18 x + 32}{( x - 9 ) ^{2}}

Find intervals:

Increasing

: - \infty < x < 2,

Decreasing

: 2 < x < 9,

Decreasing

: 9 < x < 16,

Increasing

: 16 < x < \infty

Plug

x = 2

into

\frac{x ^{2} - 11 x + 67}{x - 9} : - 7

Maximum (2, - 7)

Plug

x = 16

into

\frac{x ^{2} - 11 x + 67}{x - 9} : 21

Minimum (16, 21)

Maximum (2, - 7), Minimum (16, 21)

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

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

f (x, y) = 4 x^{4} + 4 y^{4} - 2 x y

f (x) = x^{2} + y^{2} - 4 x = 1

f (x) = x^{3} - 7 x - 6
