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)

f (x) = - 2 x^{3} - 2 y^{3} + 6 x y + 10

8 x^{3} + 2 x y - 3 x^{2} + y^{2} + 1

f (x) = 3 x^{2} - 2 x + y^{2} - 4 y + 1

P (a, b) = 2 a + b

y = x^{2} - 2 ln (x)
