Question

Use quadratic regression to find the equation of a quadratic function that fits the given points.

Answer 1

Answer:

y = 26.45 + 32.45x - 9.25x

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
