Question

Given the points graphed in the following figure , use quadratic to find the quadratic function of bestFit round theCoefficients toThree decimal places.

Answer 1

Solution:

The points are;

$(1,1),(2,3),(4,2),(3,7)$

We find that the quadratic model is;

The quadratic model with the coefficients rounded to three decimal places is;

$y=-1.750x^2+9.450x-7.250$
