extreme f(x)=49x^2-10x+17

extreme points

f (x) = 49 x^{2} - 10 x + 17

Minimum (\frac{5}{49}, \frac{808}{49})

Solution steps

f^{'} (x) = 98 x - 10

Find intervals:

Decreasing

: - \infty < x < \frac{5}{49},

Increasing

: \frac{5}{49} < x < \infty

Plug

x = \frac{5}{49}

into

49 x^{2} - 10 x + 17 : \frac{808}{49}

Minimum (\frac{5}{49}, \frac{808}{49})

f (x, y) = x^{2} + x y + y^{2} - 2 x + 2 y

f (x, y) = - 3 y^{3} - 3 x y + 13 y - 2 \cdot 2 + 5 x + 19

f (x) = x y + y - 16 x

y = x^{7} e^{x} + 4

f (x) = 2 x - \frac{2000}{x ^{2}}
