An example of a quadratic regression model is a. $Y _ { i } = \beta _ { 0 } + \beta _ { 1 } X + \beta _ { 2 } Y ^ { 2 } + u _ { i }$.
b. $Y _ { i } = \beta _ { 0 } + \beta _ { 1 } \ln ( X ) + u _ { i }$.
c. $Y _ { i } = \beta _ { 0 } + \beta _ { 1 } X + \beta _ { 2 } X ^ { 2 } + u _ { i }$.
d. $Y _ { i } ^ { 2 } = \beta _ { 0 } + \beta _ { 1 } X + u _ { i }$.
