extreme x^{19/9}+x^{10/9}

extreme

Maximum (- \frac{10}{19}, (- \frac{10}{19})^{\frac{19}{9}} + (- \frac{10}{19})^{\frac{10}{9}}), Minimum (0, 0)

Solution steps

Find the critical points:

x = - \frac{10}{19}, x = 0

Domain of

x^{\frac{19}{9}} + x^{\frac{10}{9}} : - \infty < x < \infty

Find intervals:

Increasing

: - \infty < x < - \frac{10}{19},

Decreasing

: - \frac{10}{19} < x < 0,

Increasing

: 0 < x < \infty

Plug the extreme point

x = - \frac{10}{19}

into

x^{\frac{19}{9}} + x^{\frac{10}{9}} \Rightarrow y = (- \frac{10}{19})^{\frac{19}{9}} + (- \frac{10}{19})^{\frac{10}{9}}

Maximum (- \frac{10}{19}, (- \frac{10}{19})^{\frac{19}{9}} + (- \frac{10}{19})^{\frac{10}{9}})

Plug the extreme point

x = 0

into

x^{\frac{19}{9}} + x^{\frac{10}{9}} \Rightarrow y = 0

Minimum (0, 0)

Maximum (- \frac{10}{19}, (- \frac{10}{19})^{\frac{19}{9}} + (- \frac{10}{19})^{\frac{10}{9}}), Minimum (0, 0)
