Question

given two functions f and g, one way to obtain the real solution of equation f(x) = g(x) it to graph the equation y=f(x) and y=g(x) in an xy-plane and then fine the x-coordinates of any points of intersection. Describe another way to solve f(x) = g(x) that also involves graphing in an xy-plane but that is based on the difference function f - g

Answer 1

Graph the function of (f - g)(x) and find the x-intercepts.
