extreme f(x)=4x^2-x-5

Solution

extreme

Solution

Minimum (\frac{1}{8}, - \frac{81}{16})

Solution steps

f^{'} (x) = 8 x - 1

Find intervals:

Decreasing

: - \infty < x < \frac{1}{8},

Increasing

: \frac{1}{8} < x < \infty

Plug

x = \frac{1}{8}

into

4 x^{2} - x - 5 : - \frac{81}{16}

Minimum (\frac{1}{8}, - \frac{81}{16})
