inflection f(x)=x^3-4x^2-16x+5

inflection points

f (x) = x^{3} - 4 x^{2} - 16 x + 5

(\frac{4}{3}, - \frac{569}{27})

Solution steps

f^{''} (x) = 6 x - 8

Find intervals:

Concave Downward

: - \infty < x < \frac{4}{3},

Concave Upward

: \frac{4}{3} < x < \infty

Plug

x = \frac{4}{3}

into

x^{3} - 4 x^{2} - 16 x + 5 : - \frac{569}{27}

(\frac{4}{3}, - \frac{569}{27})

y = x - 3, (2, 1)

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

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

(0, 0), (r, h)

y = ln (x + 3)
