What is the difference between linear and quadratic functions?

Linear functions have a constant rate of change and are represented by a straight line, while quadratic functions have a variable rate of change and are represented by a parabola.

How can you identify a quadratic function from a table of values?

If the second differences of the y-values are constant, the relationship is quadratic.

What is the general form of a quadratic equation?

The general form of a quadratic equation is $$Ax^2 + Bx + C = 0$$ , where $$A$$ , $$B$$ , and $$C$$ are constants.

What is regression analysis?

Regression analysis is a statistical method used to determine the relationship between variables, often used to find the best-fitting curve for a set of data.

What is the purpose of finding a curve of best fit?

The purpose is to model the relationship between variables and make predictions based on the data.

What type of function best models the average monthly temperature data over time?

Quadratic functions often model data that shows a parabolic trend, such as average monthly temperatures over time.

What is the role of the y-intercept in a quadratic function?

The y-intercept is the point where the graph intersects the y-axis, represented by the value of $$c$$ in the equation $$y = ax^2 + bx + c$$ .

How do you find the roots of a quadratic equation?

The roots can be found using the quadratic formula: $$x = \frac{-b \text{±} \text{√}(b^2 - 4ac)}{2a}$$ .
