Explanation of Solution
Given:
Two logarithmic functions:
Calculation:
Upon entering the given two equations on the TI-84 Plus calculator and then graphing them, we get the required graph as shown below:
b)
To create:
A table of values for the given functions and the graphs using the ‘table’ feature of the calculator.
b)

Answer to Problem 69E
The required table is:
Explanation of Solution
Given:
Two logarithmic functions:
Upon using the ‘table’ feature of the calculator, we get the tables for the given two functions as shown below:
c)
To conclude:
What do the graphs in part (a) and tables in part (b) conclude about the given two functions? Verify the conclusion algebraically.
c)

Answer to Problem 69E
Both the functions have the same graph and the same table. Hence both the functions are equivalent to each other.
Explanation of Solution
Given:
Two logarithmic functions:
From the graphs in part (a) and the tables in part (b), we can see that both the functions are equivalent to each others.
Algebraic verification:
Upon simplifying the first function using properties of logarithm, we get the second function.
Hence, we have verified algebraically that both the functions are the same.
