extreme f(x)=(x+2)^3(x-3)

extreme

Saddle (- 2, 0), Minimum (\frac{7}{4}, - \frac{16875}{256})

Solution steps

f^{'} (x) = (x + 2)^{2} (4 x - 7)

Find intervals:

Decreasing

: - \infty < x < - 2,

Decreasing

: - 2 < x < \frac{7}{4},

Increasing

: \frac{7}{4} < x < \infty

Plug

x = - 2

into

(x + 2)^{3} (x - 3) : 0

Saddle (- 2, 0)

Plug

x = \frac{7}{4}

into

(x + 2)^{3} (x - 3) : - \frac{16875}{256}

Minimum (\frac{7}{4}, - \frac{16875}{256})

Saddle (- 2, 0), Minimum (\frac{7}{4}, - \frac{16875}{256})
