Math Problem Statement
Solution
Let's break the problem into parts and solve step by step. The problem involves filling out tables and analyzing the exponential function and the logarithmic function .
Step 1: Fill in the table for
Using the exponential formula , calculate for each value of :
- :
- :
- :
- :
- :
So, the table is:
-2 | |
-1 | |
0 | 1 |
1 | 3 |
2 | 9 |
Step 2: Fill in the table for
Using the logarithmic formula , calculate for each value of . Recall that is the power to which must be raised to get :
- :
- :
- :
- :
- :
So, the table is:
-2 | |
-1 | |
1 | 0 |
3 | 1 |
9 | 2 |
Step 3: Fill in attributes of and
For :
- Domain: (all real numbers)
- Range: (positive real numbers)
- x-intercept: None (never crosses the x-axis)
- y-intercept:
- Asymptote: Horizontal asymptote at
For :
- Domain: (positive real numbers)
- Range: (all real numbers)
- x-intercept:
- y-intercept: None (never crosses the y-axis)
- Asymptote: Vertical asymptote at
Step 4: Plot the Graph
The graph includes:
- The exponential function
- The logarithmic function
- The line (as a reference line showing the inverse relationship).
If you'd like, I can draw the graph and display it for better understanding.
Would you like the graph or need more clarifications?
