extreme f(y)=7x-x^2+18

Solution

extreme points

f (y) = 7 x - x^{2} + 18

Solution

Maximum (\frac{7}{2}, \frac{121}{4})

Solution steps

f^{'} (x) = - 2 x + 7

Find intervals:

Increasing

: - \infty < x < \frac{7}{2},

Decreasing

: \frac{7}{2} < x < \infty

Plug

x = \frac{7}{2}

into

7 x - x^{2} + 18 : \frac{121}{4}

Maximum (\frac{7}{2}, \frac{121}{4})
