extreme-1.8x^2+7x-11

Solution

extreme points

- 1.8 x^{2} + 7 x - 11

Solution

Maximum (\frac{35}{18}, - 4.19444 \dots)

Solution steps

f^{'} (x) = - 3.6 x + 7

Find intervals:

Increasing

: - \infty < x < \frac{35}{18},

Decreasing

: \frac{35}{18} < x < \infty

Plug

x = \frac{35}{18}

into

- 1.8 x^{2} + 7 x - 11 : - 4.19444 \dots

Maximum (\frac{35}{18}, - 4.19444 \dots)

Popular Examples

extreme f(x,y)=2ln(x)+ln(y)-4x-y extreme points

f (x, y) = 2 ln (x) + ln (y) - 4 x - y

extreme f(x,y)=3x+y extreme points

f (x, y) = 3 x + y

extreme f(t)=(1+2t-3t^2+4t^3)u(t-2)extreme points

f (t) = (1 + 2 t - 3 t^{2} + 4 t^{3}) u (t - 2)

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

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

extreme f(x)=-2/5 x^5+5x^4-16x^3-19 extreme points

f (x) = - \frac{2}{5} x^{5} + 5 x^{4} - 16 x^{3} - 19
