Graphs of quadratic functions can be used to solve equations. Example Draw the graph of y = 2 x 2 + 2 x 4 for values of –3 to 2. Use the graph to solve the equation y = 2 x 2 + 2 x 4. Solution ...

The basic functions taught in high school algebra (e.g., linear, polynomial, etc.) are used to model patterns in data. We have been pursuing this possibility by developing a statistics and data ...
