Did the student find the zero for the cubic regression? 5. x˜ - 6x -16 www.algebra-worksheets.com 6. We will find a model of the form y = ax2 + bx + c, called the quadratic regression. In this method, we find out the value of a, b and c so that squared vertical distance between each given point (${x_i, y_i}$) and the parabola equation (${ y = ax^2 + bx + 2}$) is minimal. The equation can be defined in the form as a x 2 + b x + c. Quadratic regression is an extension of simple linear regression. • Calculator regression functions:
