4x + 3\) and draw its graph for values of \(x\) from –2 to 5. Plot the \(x\) and \(y\) values as coordinates and join them with a smooth curve. This is a typical shape for a quadratic function.

Instead of writing Function = multiply by 3 we can use algebra. Graphically, \(f(x) = x^2\) is the same as the graph of \(y = x^2\). Writing graphs as functions in the form of \(f(x)\) is useful ...
