Graph linear functions. Write the equation for a linear function from the graph of a line. Given the equations of two lines, determine whether their graphs are parallel or perpendicular. Write the equation of a line parallel or perpendicular to a given line. Solve a system of linear equations...
Graphs of Linear Functions A linear function is an equation that when graphed, creates a perfectly straight line. The equation for a linear function is of the form: f(x) = mx + b. The variables m and b will be replaced with numbers. The variable m represents the slope of the line ...
Describe how you would graph this line using the slope-intercept method. Be sure to write in complete sentences. Write the equation in function notation. Explain what the graph of the function represents. Be sure to use complete sentences. ...

In many polynomial regression models, adding terms to the equation increases both R2 and adjusted R2. In the preceding example, using a cubic fit increased both statistics compared to a linear fit. (You can compute adjusted R2 for the linear fit for yourself to demonstrate that it has a low...
The number of discriminant functions is the number of a priori identified groups, minus one; thus, for two groups, there would be one discriminant function [13]. For the two-group case, the form of the discriminant function equation (DFE) is: DFE = V1X1 + V2X2 + V3X3 = …ViXi + ...
The frequency-domain filter taps W0,…, WN−1 can be determined by first determining the pulse response of the corresponding time-domain filter and then transforming this filter into the frequency domain by means of a DFT. However, as mentioned above, determining the MMSE time-domain filter ...
notable extensions. In particular, when applied to multiple variables, the model has been extended to include dynamic associations between the growth factors, allowing to establish which variable, if any, is driving the change of the other variable, hence determining the leader and the lagger ...
