Answer :
The required value of function F(x), when x=18 is -2
A line of best fit is f(x) โ โ0.86x + 13.5 for the set of points in the table
x = 2 3 5 6 7 8 9
F(x) = 21 10 10 8 9 5 6
What is line?
line, is curve showing the shortest distance between 2 points.
Now, putting x = 18 in f(x) โ โ0.86x + 13.5
f(x) โ โ0.86(18) + 13.5
= -1.98
โ
-2 (approximation)
Thus, the required values of x=18 in a line of best fit is -2.
