extreme f(x)=x^2-3x-4

Solution

extreme

Solution

Minimum (\frac{3}{2}, - \frac{25}{4})

Solution steps

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

Find intervals:

Decreasing

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

Increasing

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

Plug

x = \frac{3}{2}

into

x^{2} - 3 x - 4 : - \frac{25}{4}

Minimum (\frac{3}{2}, - \frac{25}{4})
