2. consider a function f(x) that takes on values | x +2| -5 for x greater than or equal to -8, and 4x +36 for x less than -8. (i) write f(x) in good piecewise function notation. (ii) use (i) to graph this function. label the vertex of the absolute value portion. (iii) looking at your graph, the absolute value portion of the function could be itself written as a 2-part piecewise graph. so rewrite f(x) as a piecewise function with three pieces. (iv) now use (iii) to find all the zeros of this function. (v) label the points from (iv), with their coordinates, on your graph from (ii). of course, your graph is on graph paper.

Hello,

Please, see the attached files.

Thanks.

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
