extreme f(x)=-4+x-x^2

Solution

extreme points

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

Solution

Maximum (\frac{1}{2}, - \frac{15}{4})

Solution steps

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

Find intervals:

Increasing

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

Decreasing

: \frac{1}{2} < x < \infty

Plug

x = \frac{1}{2}

into

- 4 + x - x^{2} : - \frac{15}{4}

Maximum (\frac{1}{2}, - \frac{15}{4})
