extreme f(x)=(7.8x^2-225x+1709)

extreme points

f (x) = (7.8 x^{2} - 225 x + 1709)

Minimum (\frac{375}{26}, 86.40384 \dots)

Solution steps

f^{'} (x) = 15.6 x - 225

Find intervals:

Decreasing

: - \infty < x < \frac{375}{26},

Increasing

: \frac{375}{26} < x < \infty

Plug

x = \frac{375}{26}

into

7.8 x^{2} - 225 x + 1709 : 86.40384 \dots

Minimum (\frac{375}{26}, 86.40384 \dots)
