extreme f(x)=3x^2+4x-15

Solution

extreme points

f (x) = 3 x^{2} + 4 x - 15

Solution

Minimum (- \frac{2}{3}, - \frac{49}{3})

Solution steps

f^{'} (x) = 6 x + 4

Find intervals:

Decreasing

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

Increasing

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

Plug

x = - \frac{2}{3}

into

3 x^{2} + 4 x - 15 : - \frac{49}{3}

Minimum (- \frac{2}{3}, - \frac{49}{3})

Popular Examples

domain of f(x)=2-x domain

f (x) = 2 - x

domain of f(x)=e^xsqrt(x)domain

f (x) = e^{x} x

amplitude of f(x)=-4sin(12x-pi/4)+3 amplitude

f (x) = - 4 sin (12 x - \frac{π}{4}) + 3

asymptotes of f(x)=5(x+2)asymptotes

f (x) = 5 (x + 2)

domain of f(x)=(sqrt(5-x))/(5+x)domain

f (x) = \frac{5 - x}{5 + x}
