Math Problem Statement
Solution
The image contains a multiple-choice question about the difference between exponential growth and exponential decay. Here's a breakdown of the options:
-
The base for exponential growth is always a number smaller than 1 while the base for exponential decay is always a number larger than 1.
- This statement is incorrect. In exponential growth, the base is greater than 1, and for exponential decay, the base is between 0 and 1.
-
For exponential growth represented by a table, the y-values increase as the x-values increase. For exponential decay represented by a table, the y-values decrease as the x-values increase.
- This statement is correct. In exponential growth, as the x-values (typically time or another independent variable) increase, the y-values increase. For exponential decay, as the x-values increase, the y-values decrease.
-
The graph for exponential growth decreases while the graph of exponential decay increases.
- This statement is incorrect. The graph of exponential growth increases, while the graph of exponential decay decreases.
-
The formula for exponential growth is y = a(1 - r)^x while the formula for exponential decay is y = a(1 + r)^x.
- This statement is incorrect. The correct formula for exponential growth is y = a(1 + r)^x, and the formula for exponential decay is y = a(1 - r)^x.
The best answer to this question is:
"For exponential growth represented by a table, the y-values increase as the x-values increase. For exponential decay represented by a table, the y-values decrease as the x-values increase."

- What is the general form of the exponential growth and decay formulas?
- How can you identify exponential growth or decay just by looking at a graph?
- What are real-life applications of exponential growth and decay?
- How do exponential functions compare to linear functions in graphs?
- What happens if the base in an exponential function is exactly 1?
Tip: When analyzing exponential functions, remember that a base greater than 1 indicates growth, while a base between 0 and 1 indicates decay!
