Math Problem Statement
Solution
Let's analyze the four given exponential functions and their graphs. Each exponential function has a specific behavior based on its growth rate and vertical shift.
The Functions:
-
- Exponential growth due to .
- Shifted up by 3 units.
-
- Exponential decay (since exponent is negative).
- Shifted down by 6 units.
-
- Exponential growth (no multiplication factor for ).
- Shifted up by 3 units.
-
- Exponential decay (due to ).
- Shifted down by 6 units.
Graph Behavior:
- Exponential Growth: Curves moving upward and becoming steeper as increases.
- Exponential Decay: Curves approaching 0 as increases, but steeper when is negative.
Matching the Graphs:
-
Top-left graph: This graph shows an exponential growth that is shifted up. So, it should be either or . Since this graph appears steeper, it likely corresponds to .
-
Top-right graph: This graph shows exponential growth with a similar shape but a smaller vertical shift. Hence, this matches .
-
Bottom-left graph: This graph displays exponential decay with a downward shift, matching .
-
Bottom-right graph: This graph shows a sharper exponential decay and downward shift, which matches .
Final Matching:
- Top-left:
- Top-right:
- Bottom-left:
- Bottom-right:

Here are 5 related questions to explore:
- What are the general properties of exponential growth and decay functions?
- How do vertical shifts affect the graphs of exponential functions?
- How can you distinguish between exponential growth and decay based on the function?
- What is the role of the base of the exponential (like 1.5 in this case)?
- How do negative exponents influence the shape of exponential graphs?
Tip: When matching exponential functions to their graphs, always observe whether the function is growing or decaying and note any shifts up or down on the y-axis.
