extreme f(x)=x^3-7/2 x^2+2x-5

extreme

Maximum (\frac{1}{3}, - \frac{253}{54}), Minimum (2, - 7)

Solution steps

f^{'} (x) = 3 x^{2} - 7 x + 2

Find intervals:

Increasing

: - \infty < x < \frac{1}{3},

Decreasing

: \frac{1}{3} < x < 2,

Increasing

: 2 < x < \infty

Plug

x = \frac{1}{3}

into

x^{3} - \frac{7}{2} x^{2} + 2 x - 5 : - \frac{253}{54}

Maximum (\frac{1}{3}, - \frac{253}{54})

Plug

x = 2

into

x^{3} - \frac{7}{2} x^{2} + 2 x - 5 : - 7

Minimum (2, - 7)

Maximum (\frac{1}{3}, - \frac{253}{54}), Minimum (2, - 7)
