Math Problem Statement
A function f(x) = √x is transformed into the function g(x) = 2√(x + 4) - 7. Choose the 3 transformations that occurred.
Solution
Let's analyze the transformations from the given functions:
- The original function is .
- The transformed function is .
Now, let's break down the transformations:
- Vertical Stretch: The coefficient 2 in front of stretches the graph vertically. This is a vertical stretch.
- Horizontal Shift: The expression indicates a horizontal shift. Since it is , the graph is shifted 4 units to the left.
- Vertical Shift: The constant at the end subtracts 7 from the entire function, which shifts the graph 7 units down.
Conclusion:
The three transformations are:
- Vertical Stretch
- Horizontal Shift Left 4 units
- Vertical Shift Down 7
Would you like a detailed explanation of any part of this transformation?
Here are 5 questions to deepen your understanding:
- How does changing the coefficient of the square root affect the graph of the function?
- What would happen if the transformation was instead of ?
- How would the graph be different if the vertical shift was positive instead of negative?
- What is the difference between a vertical stretch and a vertical compression?
- How do you identify horizontal transformations based on the expression inside the square root?
Tip: Always remember that transformations inside the square root affect the graph horizontally, while transformations outside affect it vertically.
