inflection f(x)=x^4-32x^2+5

inflection points

f (x) = x^{4} - 32 x^{2} + 5

(- \frac{4}{3}, - \frac{1235}{9}), (\frac{4}{3}, - \frac{1235}{9})

Solution steps

f^{''} (x) = 12 x^{2} - 64

Find intervals:

Concave Upward

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

Concave Downward

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

Concave Upward

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

Plug

x = - \frac{4}{3}

into

x^{4} - 32 x^{2} + 5 : - \frac{1235}{9}

(- \frac{4}{3}, - \frac{1235}{9})

Plug

x = \frac{4}{3}

into

x^{4} - 32 x^{2} + 5 : - \frac{1235}{9}

(\frac{4}{3}, - \frac{1235}{9})

(- \frac{4}{3}, - \frac{1235}{9}), (\frac{4}{3}, - \frac{1235}{9})

y = 10 x + 2, (6, 5)

f (x) = \frac{x - 3}{x ^{2} - 5 x + 6}

f (x) = \frac{5}{x - 7}

f (x) = 2 x^{2} + 24 x + 76

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