Finding the Points of Intersection of a Linear and a Quadratic
The mathematical solution explains how to find the points of intersection of a linear and a quadratic function by solving the equations simultaneously. By rearranging the linear equation and equating to form a quadratic equation, the x values of the intersection are found by solving the equation using factorisation. The corresponding values of y are then found by substitution.
The graphical solution explains how to use the graphic calculator to verify answers by drawing the two functions and finding the coordinates of the intersections of the two graphs.
