extreme f(x)=3x^2+5x+8

Solution

extreme points

f (x) = 3 x^{2} + 5 x + 8

Solution

Minimum (- \frac{5}{6}, \frac{71}{12})

Solution steps

f^{'} (x) = 6 x + 5

Find intervals:

Decreasing

: - \infty < x < - \frac{5}{6},

Increasing

: - \frac{5}{6} < x < \infty

Plug

x = - \frac{5}{6}

into

3 x^{2} + 5 x + 8 : \frac{71}{12}

Minimum (- \frac{5}{6}, \frac{71}{12})

Popular Examples

extreme f(t)=tsqrt(4-t^2)extreme points

f (t) = t 4 - t^{2}

extreme f(x)=y^3-x^2+2y^2-4x-3 extreme points

f (x) = y^{3} - x^{2} + 2 y^{2} - 4 x - 3

extreme f(x,y)=2x^3+xy^2+5x^2+y^2+3 extreme points

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

extreme (x^2-48)/(x-7)extreme points

\frac{x ^{2} - 48}{x - 7}

extreme 4x^3-x^4 extreme points

4 x^{3} - x^{4}
