Explain why it is important to check your solution when you solve by graphing. (2 points
because that is the location where the function crosses the x axis and because you want to be correct
but if you were solving a systems of equations then that is the point of intersection
All solution methods have inherent error. "Graphing' is no different. It is ALWAYS important to check your solutions.
true and those solutions are called "extraneous" solutions
