A regression can either be linear, nonlinear or no relationship at all
The equation of the quadratic regression is [tex]y = -0.89x^2 +3.24x +11.93[/tex]
To determine the equation of the quadratic regression, we make use of a graphing calculator.
From the graphing calculator, we have the following calculator summary
- a = -0.89
- b = 3.24
- c = 11.93
A quadratic regression equation is represented as
[tex]y = ax^2 + bx + c[/tex]
So, we have:
[tex]y = -0.89x^2 +3.24x +11.93[/tex]
Hence, the equation of the quadratic regression is [tex]y = -0.89x^2 +3.24x +11.93[/tex]
