extreme y= 1/2 x^2+((14-3x)/4)^2

extreme

Minimum (\frac{42}{17}, \frac{98}{17})

Solution steps

f^{'} (x) = \frac{17 x - 42}{8}

Find intervals:

Decreasing

: - \infty < x < \frac{42}{17},

Increasing

: \frac{42}{17} < x < \infty

Plug

x = \frac{42}{17}

into

\frac{1}{2} x^{2} + (\frac{14 - 3 x}{4})^{2} : \frac{98}{17}

Minimum (\frac{42}{17}, \frac{98}{17})
