1. What are the relative minimum and relative maximum values over the interval [-4, 4] for the function shown in the graph? relative minimum = -3, relative maximum = 64

relative minimum = 0, relative maximum = 64

relative minimum = -3, relative maximum = -36

relative minimum = -36, relative maximum = 64

2. True or False? 3.  What is the equivalent degree angle measure of 5π/3 radians?

1.  The relative minimum  is the low point on the graph....this is  -36

The relative max  is the high point on the graph....this is 64

2.  f (x) = 8x^2 + 16x  + 6         g (x)  = x^3 - 3x^2  - 9

So   ( f + g) x   =    f (x) + g (x)   =

x^3  + 8x^2 - 3x^2 + 16x + 6  - 9  =

x^3  + 5x^2 + 16x - 3  ......so.....true  !!!

3.  5pi / 3

To convert to  degrees we have

5pi / 3  *    180  / pi  =

5pi / (3 pi) * 180  =

(5/3) * 180  =

5 * (180 / 3)  =

5 * 60  =
