Option 2 - f(x)=-2
Step-by-step explanation:
Given : A line of best fit is f(x) ≈ −0.86x + 13.5 for the set of points in the table.
2 12
3 10
5 10
6 8
7 9
8 5
9 6
To find : What is a good approximation for the value of the function, f(x), when x = 18?
Solution :
We have given the function,
The best fit for the value x=18, f(x) is
Approximately, For the value of x=18, f(x)=-2
Therefore, Option 2 is correct.
