Answer:
Please check the explanation.
Step-by-step explanation:
Given the table 1
x y
-12 2
-10 10
0 -2
5 -6
8 -11
15 -15
From the table, it is clear that for each input there exists a unique output.
i.e.
According to the given table,
y = 2 at x=-12
y = 10 at x=-1 0
y = -1 at x=0
y = -11 at x=8
y = -15 at x=15
From the table, it is clear that for each input x, it has a unique output y.
Hence, table 1 is a function.
Given the table 2
9 -18
-20 0
-6 1
-17 16
9 17
11 19
This table does not produce a function, because the input x=9 produces two outputs.
at x = 9, the y = -18
at x = 9, the y = 17
Therefore, the table 2 does not represent a function.
We need the figure to answer that.
12
9, 10, 4, 12, 15, 17, 18, 10, 12, 13
Putting the numbers from smallest to largest
4,9, 10, 10, 12 12, 13, 15, 17, 18,
The median is the middle number
There are 10 numbers
The middle number is between the 12's, so it is 12
