extreme 4x^3-3x^2-36x+17

extreme

Maximum (- \frac{3}{2}, \frac{203}{4}), Minimum (2, - 35)

Solution steps

f^{'} (x) = 12 x^{2} - 6 x - 36

Find intervals:

Increasing

: - \infty < x < - \frac{3}{2},

Decreasing

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

Increasing

: 2 < x < \infty

Plug

x = - \frac{3}{2}

into

4 x^{3} - 3 x^{2} - 36 x + 17 : \frac{203}{4}

Maximum (- \frac{3}{2}, \frac{203}{4})

Plug

x = 2

into

4 x^{3} - 3 x^{2} - 36 x + 17 : - 35

Minimum (2, - 35)

Maximum (- \frac{3}{2}, \frac{203}{4}), Minimum (2, - 35)
