extreme f(x)=x^2sqrt(4-x^2)

Solution

extreme points

f (x) = x^{2} 4 - x^{2}

Solution

Minimum (- 2, 0), Maximum (- \frac{2 2}{3}, \frac{16}{3 3}), Minimum (0, 0), Maximum (\frac{2 2}{3}, \frac{16}{3 3}), Minimum (2, 0)

Solution steps

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

Find intervals:

Increasing

: - 2 < x < - \frac{2 2}{3},

Decreasing

: - \frac{2 2}{3} < x < 0,

Increasing

: 0 < x < \frac{2 2}{3},

Decreasing

: \frac{2 2}{3} < x < 2

Plug

x = - 2

into

x^{2} 4 - x^{2} : 0

Minimum (- 2, 0)

Plug

x = - \frac{2 2}{3}

into

x^{2} 4 - x^{2} : \frac{16}{3 3}

Maximum (- \frac{2 2}{3}, \frac{16}{3 3})

Plug

x = 0

into

x^{2} 4 - x^{2} : 0

Minimum (0, 0)

Plug

x = \frac{2 2}{3}

into

x^{2} 4 - x^{2} : \frac{16}{3 3}

Maximum (\frac{2 2}{3}, \frac{16}{3 3})

Plug

x = 2

into

x^{2} 4 - x^{2} : 0

Minimum (2, 0)

Minimum (- 2, 0), Maximum (- \frac{2 2}{3}, \frac{16}{3 3}), Minimum (0, 0), Maximum (\frac{2 2}{3}, \frac{16}{3 3}), Minimum (2, 0)
