extreme f(x)=-x^2+3x+1

Solution

extreme points

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

Solution

Maximum (\frac{3}{2}, \frac{13}{4})

Solution steps

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

Find intervals:

Increasing

: - \infty < x < \frac{3}{2},

Decreasing

: \frac{3}{2} < x < \infty

Plug

x = \frac{3}{2}

into

- x^{2} + 3 x + 1 : \frac{13}{4}

Maximum (\frac{3}{2}, \frac{13}{4})

Popular Examples

extreme f(x)=x^3-3x+y^2 extreme points

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

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

f (x, y) = x^{4} - 4 x y + 2 y^{2}

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

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

extreme f(x,y)=sqrt(1-(x^2)/4-(y^2)/4)extreme points

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

extreme f(x)=x^3-3x^2-24x+32 extreme points

f (x) = x^{3} - 3 x^{2} - 24 x + 32
