Quadratic Regression Practice

Quadratic regression is a type of regression analysis used to model the relationship between a dependent variable and one or more independent variables by fitting a quadratic equation to the data.

The vertex represents the maximum or minimum point of the parabola, depending on the direction it opens.

The line of best fit, or regression line, is used to summarize the relationship between variables and make predictions based on the data.

Linear regression fits a straight line to the data, while quadratic regression fits a parabolic curve, allowing for more complex relationships.

To estimate a value using a quadratic regression equation, substitute the independent variable's value into the equation and solve for the dependent variable.

Rounding a number to two decimal places means adjusting the number so that it has only two digits after the decimal point.
