extreme f(x)=((x^2-63))/(x-8)

extreme points

f (x) = \frac{( x ^{2} - 63 )}{x - 8}

Maximum (7, 14), Minimum (9, 18)

Solution steps

f^{'} (x) = \frac{x ^{2} - 16 x + 63}{( x - 8 ) ^{2}}

Find intervals:

Increasing

: - \infty < x < 7,

Decreasing

: 7 < x < 8,

Decreasing

: 8 < x < 9,

Increasing

: 9 < x < \infty

Plug

x = 7

into

\frac{x ^{2} - 63}{x - 8} : 14

Maximum (7, 14)

Plug

x = 9

into

\frac{x ^{2} - 63}{x - 8} : 18

Minimum (9, 18)

Maximum (7, 14), Minimum (9, 18)

x^{3} + 8 y^{3} - 6 x y + 5

f (x) = 4 x^{3} - 60 x^{2} + 200 x

f (x) = x^{3} + 2 y^{2} + 3 x y + 8

f (x, y) = x^{2} + x y + y^{2} - 6 x - 9 y

\frac{x + 3}{x + 2}
