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.

All quadratic functions ... graph of \(y = ax^2 + bx + c \) is drawn, the solutions to the equation are the values of the x-coordinates of the points where the graph crosses the x-axis. Draw ...
