Question

What are the relative minimum and relative maximum values over the interval [−4,4] for the function shown in the graph?

Answer 1

Answer:

Relative minimum :  -36

Relative maximum :  64

The rate of change is 336 greater

Step-by-step explanation:

Relative minimum are the minimum values  in the interval

Looking at the graph, we find the lowest point in the interval

Relative minimum : (-3, -36) and (3,-36)  y value -36

Looking at the graph, we find the highest point in the interval

Relative maximum : (0,64)  y value 64

Average rate of change = f(x2) - f(x1)

                                          ---------------

                                            x2 - x1

                                       

                                         f(7) - f(5)     1469 - 549      920

                                        ------------- = ---------------   = ------- = 460

                                             7-5               7-5                2

                                         f(4) - f(2)     287 - 39         248

                                        ------------- = ---------------   = ------- = 124

                                             4-2               4-2                2

We need to subtract

460-124

336

Answer 2

The relative minimum would be the Y value of the lowest point of the curved the line which is -36.

The relative maximum would be the Y value of the highest point of the curved line which is at 64.

Answer: relative minimum = −36 , relative maximum = 64

Rate of change between [5,7]

At 5 y = 549 at 7 y = 1469

Rate of change = change in y over change in x:

1469 - 549 / 7-5 = 920/2 = 460

Rate of change between [2,4]

At 2 y = 39, at 4 y = 287

Rate of change:

287 - 39 / 4-2 = 248/2 = 124

Now subtract the two: 460 - 124 = 336 greater
