Part A
To graph this, we plot open holes at -2 and 3 on the number line. Shade between these open holes to represent values between -2 and 3, but we don't include the endpoints.
See figure 1 below.
===============================================
Part B
Solve the first inequality to get
Now solve the second inequality
We have
The graph will have an open hole at -3 and a closed/filled in circle at 1. We shade everywhere but the region between these marked values. The left portion in blue represents stuff smaller than -3; the right portion in red represents values equal to 1 or larger.
See figure 2 below.

Step-by-step explanation:
Hello!
You have the growth of 12 plants over a week (cm)
To construct a box plot you have to identify the 1st, 2nd, and 3rd Quartiles for the box and the maximum and minimum values for the whiskers.
Box
1st Quartile (Q₁)
Is the value of the data set that separates the bottom 25% from the top 75%. First, you need to calculate its position:
PosQ₁= n/4= 12/4= 3
So the first quartile is the third value.
6, 7, 7, 8, 8, 8, 9, 9, 10, 11, 11, 14
Q₁= 7
2nd Quartile/ Median (Q₂/Me)
PosMe= 12/2= 6
The second quartile in the 6th value.
6, 7, 7, 8, 8, 8, 9, 9, 10, 11, 11, 14
Q₂=Me= 8
3rd Quartile (Q₃)
PosQ₃= n*(3/4)= 12*(3/4)= 9
The third quartile is the 9th value.
6, 7, 7, 8, 8, 8, 9, 9, 10, 11, 11, 14
Q₃= 10
The left whisker extends from the Q₁ to the minimum value.
The right whisker extends from the Q₃ to the maximum value.
Min= 6
Max= 14
'------| | |-------'
6 7 8 10 14
The box plot that best displays a summary of the data, is C.
I hope this helps!
