inflection f(x)=x^3-3x^2-45x

Solution

inflection points

f (x) = x^{3} - 3 x^{2} - 45 x

Solution

(1, - 47)

Solution steps

f^{''} (x) = 6 x - 6

Find intervals:

Concave Downward

: - \infty < x < 1,

Concave Upward

: 1 < x < \infty

Plug

x = 1

into

x^{3} - 3 x^{2} - 45 x : - 47

(1, - 47)
