extreme f(x)=9x^2-x+1

Solution

extreme points

f (x) = 9 x^{2} - x + 1

Solution

Minimum (\frac{1}{18}, \frac{35}{36})

Solution steps

f^{'} (x) = 18 x - 1

Find intervals:

Decreasing

: - \infty < x < \frac{1}{18},

Increasing

: \frac{1}{18} < x < \infty

Plug

x = \frac{1}{18}

into

9 x^{2} - x + 1 : \frac{35}{36}

Minimum (\frac{1}{18}, \frac{35}{36})
