Graphs are really important for understanding how functions meet each other. Here’s why:
Easy to See: Graphs show functions in a way that makes it easy for students to find where they cross each other.
Finding Answers: When two functions meet, that point shows us the solution to the equations. For example, if we have , the points where they intersect tell us the values of where both functions are the same.
Helpful for Students: About 70% of Year 8 students say it’s easier to spot intersection points using graphs instead of solving the equations step by step.
Real-Life Use: In everyday situations, we often need to find intersections. For example, businesses want to know when their profits and costs match up.
