extreme f(x)=16x+21x^{16/21}

extreme

Minimum (- 1, 5), Maximum (0, 0)

Solution steps

f^{'} (x) = 16 + \frac{16}{x ^{\frac{5}{21}}}

Find intervals:

Decreasing

: - \infty < x < - 1,

Increasing

: - 1 < x < \infty

Plug

x = - 1

into

16 x + 21 x^{\frac{16}{21}} : 5

Minimum (- 1, 5)

Plug

x = 0

into

16 x + 21 x^{\frac{16}{21}} : 0

Maximum (0, 0)

Minimum (- 1, 5), Maximum (0, 0)
