inflection 8xe^{7x}

Solution

inflection points

8 x e^{7 x}

Solution

(- \frac{2}{7}, - \frac{16}{7 e ^{2}})

Solution steps

f^{''} (x) = 8 (49 e^{7 x} x + 14 e^{7 x})

Find intervals:

Concave Downward

: - \infty < x < - \frac{2}{7},

Concave Upward

: - \frac{2}{7} < x < \infty

Plug

x = - \frac{2}{7}

into

8 x e^{7 x} : - \frac{16}{7 e ^{2}}

(- \frac{2}{7}, - \frac{16}{7 e ^{2}})
