To explain: The way by which sketching the graph of a quadratic system can help to solve the system.

Answer to Problem 54HP
Sketching the graph of the parabolas helps to find the solutions or check if there are solutions for system.
Explanation of Solution
Sketching the graph of the parabolas helps to find the solutions or check if there are solutions for system by simply looking at the intersection points of the graph. If system does not have any intersection point that means there is no solution of the system. The number of intersection points represents the same number of solutions which means if the system has two intersection points then the system has two solutions and so on.
Therefore, sketching the graph of the parabolas helps to find the solutions or check if there are solutions for system
