inflection x^3+x^2-4x-4

Solution

inflection points

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

Solution

(- \frac{1}{3}, - \frac{70}{27})

Solution steps

f^{''} (x) = 6 x + 2

Find intervals:

Concave Downward

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

Concave Upward

: - \frac{1}{3} < x < \infty

Plug

x = - \frac{1}{3}

into

x^{3} + x^{2} - 4 x - 4 : - \frac{70}{27}

(- \frac{1}{3}, - \frac{70}{27})

domain of f(x)=sqrt(x/(x^2-9))domain

f (x) = \frac{x}{x ^{2} - 9}

inverse of f(x)= 2/x+1 inverse

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

intercepts of x^2-x-2 intercepts
