Comparing the algebraic and graphical methods for solving equations.
Both the method gives same result.
By using algebric method solve the equation it gives exact answer and also the process is helps to understand the algebric structure of the equation.
In some equations it is impossible to issolate , in this case graphical method is best to solve the equation.
Solve the equation by using graphical method gives a numerical approximation to answer.
It is also useful to us how the solution is related to other values of the variable.
For example, consider the equation .
Solve the equation by using algebraic method first.
Hence, the solution is
Solve this equation by using graphical method.
Move all terms to one side and set equal to .
Sketch the graph to find the value of where .
Sketch the graph of :
From the graph, observe that when .
Hence, the solution is .
