extreme f(x)=e^{(x)}(2x^2+x-8)

extreme points

f (x) = e^{(x)} (2 x^{2} + x - 8)

Maximum (- \frac{7}{2}, \frac{13}{e ^{\frac{7}{2}}}), Minimum (1, - 5 e)

Solution steps

f^{'} (x) = e^{x} (x - 1) (2 x + 7)

Find intervals:

Increasing

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

Decreasing

: - \frac{7}{2} < x < 1,

Increasing

: 1 < x < \infty

Plug

x = - \frac{7}{2}

into

e^{x} (2 x^{2} + x - 8) : \frac{13}{e ^{\frac{7}{2}}}

Maximum (- \frac{7}{2}, \frac{13}{e ^{\frac{7}{2}}})

Plug

x = 1

into

e^{x} (2 x^{2} + x - 8) : - 5 e

Minimum (1, - 5 e)

Maximum (- \frac{7}{2}, \frac{13}{e ^{\frac{7}{2}}}), Minimum (1, - 5 e)

f (x) = - ∣ x ∣ + 3

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

f (x) = \frac{( x ^{2} - 3 x - 18 )}{x}

(- 1, 1), (- 5, 2)

\frac{1 + x}{3 - x}
