How To Master Quadratic Regression
Similar to functions, quadratic regression is a way to model a relationship between two sets of independent variables. Quadratic regression is the process of determining the equation of a parabola that best fits a set of data. This set of data is a given set of graph points that make up the shape of a parabola. The equation of the parabola is y = ax2 + bx + c, where a can never equal zero.
The graphs of quadratic functions have a nonlinear “U”-shape with exponential curves on either side of a single intercepting y-value. We’ll show you how to use this equation.
How To Use the Leading Coefficient Test To Graph End Behavior
You can use the leading coefficient test to figure out end behavior of the graph of a polynomial function. This isn’t some complicated theorem. There’s no factoring or x-intercepts. Here are two steps you need to know when graphing polynomials for their left and right end behavior.
