extreme y=9x^3-7

Solution

extreme points

y = 9 x^{3} - 7

Solution

Saddle (0, - 7)

Solution steps

f^{'} (x) = 27 x^{2}

Find intervals:

Increasing

: - \infty < x < 0,

Increasing

: 0 < x < \infty

Plug

x = 0

into

9 x^{3} - 7 : - 7

Saddle (0, - 7)

Popular Examples

extreme x^3-12x^2+45x+8 extreme points

x^{3} - 12 x^{2} + 45 x + 8

extreme |x^4-4x^2-2|,-2<= x<= 2 extreme points

x^{4} - 4 x^{2} - 2, - 2 \leq x \leq 2

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

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

extreme f(x)=(8x)/(x^2+1)extreme points

f (x) = \frac{8 x}{x ^{2} + 1}

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

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