Math Problem Statement
Solution
The problem requires using transformations of the basic quadratic function to match the new graph shown.
Observations:
- The basic quadratic function has a vertex at and opens upwards.
- In the given transformed graph, the vertex has shifted downward, and the new graph opens upwards as well, but it is vertically stretched.
Step-by-step analysis:
-
Vertical Shift: The vertex in the new graph is at rather than . This indicates a downward shift by 6 units.
- So, the transformation includes: .
-
Vertical Stretch: The graph appears narrower, which suggests a vertical stretch. The basic quadratic function passes through points like , but in the transformed graph, this point seems to be stretched to higher values.
- We need to multiply the function by a constant to account for the stretch.
Let’s estimate the stretch factor using one of the points from the graph.
- From the table, at , the value is .
- In the transformed graph, at , the value seems to be about .
Thus, the stretch factor satisfies:
Conclusion:
The transformation involves a vertical stretch by a factor of 9 and a downward shift by 6 units. Thus, the rule that would produce the given graph is:
Would you like further details or have any questions about the transformations?
Here are 5 relative questions to deepen your understanding:
- How would the graph look if the quadratic function were horizontally shifted?
- What would happen if we applied a reflection over the x-axis to this graph?
- Can you explain how a vertical compression would affect the graph?
- How does the value of in the equation impact the shape of the parabola?
- What if the transformation included both horizontal and vertical shifts?
Tip: When applying transformations, always handle shifts first (up/down or left/right), then apply stretches or compressions, and lastly reflections if necessary.
