Answer:

Option C) Quadratic regression model

Step-by-step explanation:

Quadratic regression model

  • It is regression model in which states a non-linear relationship between the independent and dependent variables.
  • It includes the dependent variable and the square of the independent variable.
  • [tex]\hat{y}= b_0 + b_1x + b_2x^2[/tex]

where x is the independent variable and [tex]\hat{y}[/tex] is the dependent variable.

  • It is also referred to as second-order polynomial model.
  • It is used when the data shape resembles to a parabola.

Thus, the correct answer is

Option C) Quadratic regression model
