extreme f(x)= x/(x^2-x+16),0<= x<= 12

extreme points

f (x) = \frac{x}{x ^{2} - x + 16}, 0 \leq x \leq 12

Minimum (0, 0), Maximum (4, \frac{1}{7}), Minimum (12, \frac{3}{37})

Solution steps

Find the critical points:

x = 0, x = 4, x = 12

Domain of

\frac{x}{x ^{2} - x + 16}, 0 \leq x \leq 12 : 0 \leq x \leq 12

Find intervals:

Increasing

: 0 < x < 4,

Decreasing

: 4 < x < 12

Plug the extreme point

x = 0

into

\frac{x}{x ^{2} - x + 16} \Rightarrow y = 0

Minimum (0, 0)

Plug the extreme point

x = 4

into

\frac{x}{x ^{2} - x + 16} \Rightarrow y = \frac{1}{7}

Maximum (4, \frac{1}{7})

Plug the extreme point

x = 12

into

\frac{x}{x ^{2} - x + 16} \Rightarrow y = \frac{3}{37}

Minimum (12, \frac{3}{37})

Minimum (0, 0), Maximum (4, \frac{1}{7}), Minimum (12, \frac{3}{37})

f (x) = \frac{x + 3}{x ^{2} - 5 x - 24}

f (x, y) = 400 - 4 x^{2} - 25 y^{2}

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

f (x) = 10 + 3 x - x^{2}

f (x, y) = x^{3} + 3 x y - y^{3}

What is the extreme f(x)= x/(x^2-x+16),0<= x<= 12 ?
The extreme f(x)= x/(x^2-x+16),0<= x<= 12 is Minimum(0,0),Maximum(4, 1/7),Minimum(12, 3/37)
