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

extreme

Minimum (- 2, 0), Maximum (0, 2), Minimum (2, 0)

Solution steps

Find the critical points:

x = - 2, x = 0, x = 2

Domain of

4 - x^{2}, - 2 \leq x \leq 2 : - 2 \leq x \leq 2

Find intervals:

Increasing

: - 2 < x < 0,

Decreasing

: 0 < x < 2

Plug the extreme point

x = - 2

into

4 - x^{2} \Rightarrow y = 0

Minimum (- 2, 0)

Plug the extreme point

x = 0

into

4 - x^{2} \Rightarrow y = 2

Maximum (0, 2)

Plug the extreme point

x = 2

into

4 - x^{2} \Rightarrow y = 0

Minimum (2, 0)

Minimum (- 2, 0), Maximum (0, 2), Minimum (2, 0)

What is the extreme f(x)=sqrt(4-x^2),-2<= x<= 2 ?
The extreme f(x)=sqrt(4-x^2),-2<= x<= 2 is Minimum(-2,0),Maximum(0,2),Minimum(2,0)
