Explain why the x-coordinates of the points where the graphs of the equations y = f and y = g intersect are the solutions of the equation f = g; find the solutions approximately, e.g., using technology to graph the functions, make tables of values, or find successive approximations. Include cases where f and/or g are linear, polynomial, rational, absolute value, exponential, and logarithmic functions.
