Front

What does the vertex of a quadratic function represent?

Back

The vertex of a quadratic function is the highest or lowest point on the graph, depending on whether the parabola opens upwards or downwards.

What is the significance of the 'a' value in a quadratic function?

Back

The 'a' value determines the direction of the parabola (upward if a > 0, downward if a < 0) and affects the width of the parabola.

Front

How can you use quadratic regression?

Back

Quadratic regression is used to model data that follows a parabolic trend, allowing predictions based on the fitted quadratic equation.

How do you interpret the coefficients in a quadratic regression model?

Back

In a quadratic regression model, the coefficient 'a' affects the curvature, 'b' affects the slope at the vertex, and 'c' represents the y-intercept.
