The graphs of two polynomial equations do not intersect. Kelly concludes that the system has no solution. Which statement best explains why Kelly’s reasoning is correct or incorrect? A.) She is incorrect because systems may have only complex solutions which are not visible on a graph.
B.) She is incorrect because the solutions may have multiplicity greater than 1.
C.) She is correct because all solutions are intersection points of the graphs.
D.) She is correct because the solutions are irrational.

A- She is incorrect because systems may have only complex solutions which are not visible on the graph
