extreme f(x)=-0.1x^2+0.8x+98.8

extreme points

f (x) = - 0.1 x^{2} + 0.8 x + 98.8

Maximum (4, 100.4)

Solution steps

f^{'} (x) = - 0.2 x + 0.8

Find intervals:

Increasing

: - \infty < x < 4,

Decreasing

: 4 < x < \infty

Plug

x = 4

into

- 0.1 x^{2} + 0.8 x + 98.8 : 100.4

Maximum (4, 100.4)

\frac{e ^{x}}{6 + e ^{x}}

- 3 sin (2 x + \frac{π}{2})

y = 8

x - 3 y = 5

y = x^{3}
