extreme f(x)=-4x^2+40x-60

Solution

extreme points

f (x) = - 4 x^{2} + 40 x - 60

Solution

Maximum (5, 40)

Solution steps

f^{'} (x) = - 8 x + 40

Find intervals:

Increasing

: - \infty < x < 5,

Decreasing

: 5 < x < \infty

Plug

x = 5

into

- 4 x^{2} + 40 x - 60 : 40

Maximum (5, 40)

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

extreme f(x)=9x^2+3 extreme points

f (x) = 9 x^{2} + 3

extreme 2x^2-6x+(20)/x+30 extreme points

2 x^{2} - 6 x + \frac{20}{x} + 30

extreme f(x)=x^2-8x,-infinity <x<= 8 extreme points

f (x) = x^{2} - 8 x, - \infty < x \leq 8

extreme 5x+5sin(x),0<= x<= 2pi extreme points

5 x + 5 sin (x), 0 \leq x \leq 2 π
