B is the right answer
f(x) = x-3

x= y-3
x+3 =y
f^-1(x) = x+3
Answer:
Minimum value = 2
Maximum value = 26
Lower quartile = 4
Median = 14
Upper quartile = 20.5
Step-by-step explanation:
Five number summary:
- Minimum value
- Maximum value
- Lower quartile
- Median
- Upper quartile
Assuming the stem is the tens column and the leaves are units, the data values are:
2, 2, 3, 5, 7, <u>13, 15</u>, 16, 20, 21, 24, 26
Minimum value = 2
Maximum value = 26
<u>Median</u> - middle value
As there is an even number of data values, the median is the mean of the 6th and 7th data values.
Median = (13 + 15) ÷ 2 = 14
<u>Lower quartile</u>
As there is an even number of data values, the lower quartile is the mean of the 3rd and 4th data values.
Lower quartile = (3 + 5) ÷ 2 = 4
<u>Upper quartile</u>
As there is an even number of data values, the upper quartile is the mean of the 20th and 21st data values.
Lower quartile = (20 + 21) ÷ 2 = 20.5
