I will one only and you do the rest.
Let x = -2
Plug into given function.
f(-2) = 2 - 5(-2)
f(-2) = 2 + 10
f(-2) = 12
So, when x = -2, f(x) = 12.
Table:
x............ f(x)
-2 12
-1
0
1
2
Find the rest the same way.
An unknown variable ..............
Answer: Mean: 9
MAD: 46
Step-by-step explanation:
I will show u how to work out the mean
and the mad so u know
MEAN:
The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
MAD:
1) To find the mean absolute deviation of the data, start by finding the mean of the data set.
2 )Find the sum of the data values, and divide the sum by the number of data values.
3) Find the absolute value of the difference between each data value and the mean: |data value – mean.
