I believe the answer is -(2+x)/(2x-4)
Answer:
0
Step-by-step explanation:
To graph
graph the point (3,6)
yintercept is on the y axis so go up 2 units from the origin and plot the point (0,2)
now the parabola
we know it has to go through points (3,6) and (0,2)
therefor we now that it opens down
we also knwo that the vertex's y value is the axis of symmetry
so we also put a point at (6,2)
draw a parabola opening down through the points (0,2) (3,6) (6,2), with (3,6) at the top/peak

Answer:
-- Mean
Step-by-step explanation:
Given
n = 30
Data: 2 3 1 2 6 4 2 1 5 3 2 3 1 2 2 1 3 1 2 2 4 2 1 2 9 3 2 1 1 3
Solving (a): The mean
This is calculated as:
Solving (b): The median
First arrange the given data
Arranged: 1 1 1 1 1 1 1 1 2 2 2 2 2 2 2 2 2 2 2 3 3 3 3 3 3 4 4 5 6 9
This implies that the median is the average of the 15th and 16th item
Solving (c): The mode
From the given data; 2 has the highest frequency of 11.
So,
Solving (d): The Range
The highest is 9 and the lowest is 1,
So:
Solving (e): Lower (Q1) and Upper (Q3) quartile.
Q1 is calculated as:
-- from the arranged data
Q3 is calculated as:
-- from the arranged data
Solving (f): The interquartile range (IQR)
