To calculate:the values for the product of the functions
Answer to Problem 21E
The value of the functions and product of the functions for different values of x are,
The graph of the functions
Explanation of Solution
Given information:
The functions,
Formula used:
The multiplication or product of the functions
Calculation:
Consider the provided functions,
Recall the multiplication or product of the functions
Evaluate the value of
Multiply the first term of the first bracket with the terms in second bracket and do the same with the second term of the first bracket.
Combine the like terms,
Therefore, the value of product of the function is
Now, evaluate the value of the individual function
