extreme f(x)=(x^2-10x+25)/(x-8)

extreme

Maximum (5, 0), Minimum (11, 12)

Solution steps

f^{'} (x) = \frac{x ^{2} - 16 x + 55}{( x - 8 ) ^{2}}

Find intervals:

Increasing

: - \infty < x < 5,

Decreasing

: 5 < x < 8,

Decreasing

: 8 < x < 11,

Increasing

: 11 < x < \infty

Plug

x = 5

into

\frac{x ^{2} - 10 x + 25}{x - 8} : 0

Maximum (5, 0)

Plug

x = 11

into

\frac{x ^{2} - 10 x + 25}{x - 8} : 12

Minimum (11, 12)

Maximum (5, 0), Minimum (11, 12)
