Concept explainers
Comparing the algebraic and graphical methods for solving equations.
Answer to Problem 75E
Both the method gives same result.
Explanation of Solution
Calculation:
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
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.
Now,
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
Sketch the graph of
From the graph, observe that
Hence, the solution is
