The graphs of y=f(x) and y=g(x) intersect at the point (a,b). Complete the paragraph about the equation f(x)=g(x). The point (a,b) lies on the graphs of both y=f(x) and y=g(x). This means that _______, and also that________. So, the equation _________ is true. Therefore, the value ___________ must be a solution of the equation f(x)=g(x).
