extreme f(x)=-1/50 x^2+1.85x-8.5

extreme points

f (x) = - \frac{1}{50} x^{2} + 1.85 x - 8.5

Maximum (\frac{185}{4}, 34.28125)

Solution steps

f^{'} (x) = - 0.04 x + 1.85

Find intervals:

Increasing

: - \infty < x < \frac{185}{4},

Decreasing

: \frac{185}{4} < x < \infty

Plug

x = \frac{185}{4}

into

- \frac{1}{50} x^{2} + 1.85 x - 8.5 : 34.28125

Maximum (\frac{185}{4}, 34.28125)

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

f (x, y) = x^{2} - 2 \cdot x + 2 \cdot y^{2} - 4 \cdot y

f (x) = 0.00397 t^{2} - 0.593 t + 33.718

f (x) = f (x) = e x - x, - 4 \leq x \leq 2

f (x) = 4 x^{2} - 48 x + 190
