extreme f(x)=x^2+3,-1<= x<= 4

extreme

Maximum (- 1, 4), Minimum (0, 3), Maximum (4, 19)

Solution steps

Find the critical points:

x = - 1, x = 0, x = 4

Domain of

x^{2} + 3, - 1 \leq x \leq 4 : - 1 \leq x \leq 4

Find intervals:

Decreasing

: - 1 < x < 0,

Increasing

: 0 < x < 4

Plug the extreme point

x = - 1

into

x^{2} + 3 \Rightarrow y = 4

Maximum (- 1, 4)

Plug the extreme point

x = 0

into

x^{2} + 3 \Rightarrow y = 3

Minimum (0, 3)

Plug the extreme point

x = 4

into

x^{2} + 3 \Rightarrow y = 19

Maximum (4, 19)

Maximum (- 1, 4), Minimum (0, 3), Maximum (4, 19)

What is the extreme f(x)=x^2+3,-1<= x<= 4 ?
The extreme f(x)=x^2+3,-1<= x<= 4 is Maximum(-1,4),Minimum(0,3),Maximum(4,19)
