extreme f(x)=-2x^2-3x+5

Solution

extreme points

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

Solution

Maximum (- \frac{3}{4}, \frac{49}{8})

Solution steps

f^{'} (x) = - 4 x - 3

Find intervals:

Increasing

: - \infty < x < - \frac{3}{4},

Decreasing

: - \frac{3}{4} < x < \infty

Plug

x = - \frac{3}{4}

into

- 2 x^{2} - 3 x + 5 : \frac{49}{8}

Maximum (- \frac{3}{4}, \frac{49}{8})

Popular Examples

extreme 1/x+xy-8/y extreme points

\frac{1}{x} + x y - \frac{8}{y}

extreme f(x,y)=y*ln(x)extreme points

f (x, y) = y \cdot ln (x)

extreme f(x)=x^2+xy+y^2-37y+456 extreme points

f (x) = x^{2} + x y + y^{2} - 37 y + 456

extreme f(x)=4-2(x-1)^{2/3}extreme points

f (x) = 4 - 2 (x - 1)^{\frac{2}{3}}

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

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