inflection f(x)=x^4-3x^2

inflection points

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

(- \frac{1}{2}, - \frac{5}{4}), (\frac{1}{2}, - \frac{5}{4})

Solution steps

f^{''} (x) = 12 x^{2} - 6

Find intervals:

Concave Upward

: - \infty < x < - \frac{1}{2},

Concave Downward

: - \frac{1}{2} < x < \frac{1}{2},

Concave Upward

: \frac{1}{2} < x < \infty

Plug

x = - \frac{1}{2}

into

x^{4} - 3 x^{2} : - \frac{5}{4}

(- \frac{1}{2}, - \frac{5}{4})

Plug

x = \frac{1}{2}

into

x^{4} - 3 x^{2} : - \frac{5}{4}

(\frac{1}{2}, - \frac{5}{4})

(- \frac{1}{2}, - \frac{5}{4}), (\frac{1}{2}, - \frac{5}{4})

(1, 3), (5, 6)

f (x) = \frac{6}{6 - x}

f (x) = 2 x + 16

f (x) = \frac{35}{x ( x + 7 )}

\frac{x + 4}{x ^{2} - 4}
