Specification References: N6.7h N6.7h Find the intersection points of the graphs of a linear and quadratic function, knowing that these are the approximate solutions of the corresponding simultaneous equations representing the linear and quadratic functions. |
Candidates will be expected to know that the roots of an equation f(x) = 0 can be found where the graph of the function intersects the x-axis and that the solution of f(x) = a is found where y = a intersects with f(x).
