monotone x^3-x^2-4x

Solution

monotone intervals

x^{3} - x^{2} - 4 x

Solution

Increasing : - \infty < x < \frac{- 13 + 1}{3}, Decreasing : \frac{- 13 + 1}{3} < x < \frac{13 + 1}{3}, Increasing : \frac{13 + 1}{3} < x < \infty

Solution steps

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

Find intervals:

Increasing

: - \infty < x < \frac{- 13 + 1}{3},

Decreasing

: \frac{- 13 + 1}{3} < x < \frac{13 + 1}{3},

Increasing

: \frac{13 + 1}{3} < x < \infty

Increasing : - \infty < x < \frac{- 13 + 1}{3}, Decreasing : \frac{- 13 + 1}{3} < x < \frac{13 + 1}{3}, Increasing : \frac{13 + 1}{3} < x < \infty

y = - 3 x + 3

domain of f(x)=sqrt(7x+20)domain

f (x) = 7 x + 20

intercepts of f(x)=9x-7y=14 intercepts

f (x) = 9 x - 7 y = 14

domain of f(x)=4(1.5)^x-3 domain

f (x) = 4 (1.5)^{x} - 3

extreme f(x)=-x^3+2x^2+15x-5 extreme points

f (x) = - x^{3} + 2 x^{2} + 15 x - 5
