Given:
The three points are (-7,134), (-3,10) and (5,50).
To find:
The equation of parabola using quadratic regression.
Solution:
The general equation of quadratic regression is
...(i)
The three points are (-7,134), (-3,10) and (5,50).
Using the graphing calculator, we get a=3, b=-1 and c=-20. Putting these values in (i), we get


Therefore, the equation of parabola is
and the missing values in the given equation are 3, -1 and -20.
Looks like (0,1) and (2,4) are on the line.
(0,1) is the y intercept, b=1
The slope is m=(4 - 1)/(2 - 0) = 3/2
Answer: y = (3/2) x + 1
