Step-by-step explanation:
Given the data:
X : _____ 0 _____ 1 ______2 _______ 3
Y : _____29 ____42 _____62 ______ 38
The quadratic regression model has the general equation :
y=A+Bx+Cx2
Fitting the data using a quadratic regression calculator, the equation of best fit obtained is ;
y = 26.45 + 32.45x - 9.25x
