At the point (or points) where two graphs intersect, the \(x\) and \(y\) values are the same for both functions. We use this information to find the solution to simultaneous linear equations.

If we set β = f(1), then for any real number x, we have f(x) = βx and the graph of this function is the straight line in the plane passing through the origin with slope β.

A project headed by the SEI’s Scott McMillan took a step in 2020 toward standardizing graph algorithm application development in C++.

Unlike a linear, graph, ... Graphs of quadratic functions can be used to solve equations. Example. Draw the graph of \(y = 2x^{2} + 2x – 4\) for values of –3 to 2.
