extreme f(x)=6-8x,-8<= x<= 6

extreme points

f (x) = 6 - 8 x, - 8 \leq x \leq 6

Maximum (- 8, 70), Minimum (6, - 42)

Solution steps

Find the critical points:

x = - 8, x = 6

Domain of

6 - 8 x, - 8 \leq x \leq 6 : - 8 \leq x \leq 6

Find intervals:

Decreasing

: - 8 < x < 6

Plug the extreme point

x = - 8

into

6 - 8 x \Rightarrow y = 70

Maximum (- 8, 70)

Plug the extreme point

x = 6

into

6 - 8 x \Rightarrow y = - 42

Minimum (6, - 42)

Maximum (- 8, 70), Minimum (6, - 42)

2 x^{5} - 15 x^{4} + 30 x^{3} - 6

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

p (a, c) = a + 8 + c

f (x) = - 2 - x - x^{2}

f (x) = \frac{x - 1}{x ^{2} + 3 x}

What is the extreme f(x)=6-8x,-8<= x<= 6 ?
The extreme f(x)=6-8x,-8<= x<= 6 is Maximum(-8,70),Minimum(6,-42)
