Math Problem Statement

The diagram shows the graph of y = f(x) with a maximum turning point at (-2, 5) and a minimum turning point at (3, -1). Sketch the graph of y = f(x + 3) + 2.

Solution

The given problem shows the graph of a function y=f(x)y = f(x) with:

  • A maximum turning point at (2,5)(-2, 5)
  • A minimum turning point at (3,1)(3, -1)

You are asked to sketch the graph of y=f(x+3)+2y = f(x + 3) + 2.

Explanation:

  1. Horizontal Shift:

    • The expression f(x+3)f(x + 3) indicates a horizontal shift of the graph by 3 units to the left. This means every point on the original graph moves 3 units to the left along the x-axis.
  2. Vertical Shift:

    • The +2+2 outside the function indicates a vertical shift of 2 units upwards. This moves every point on the graph up by 2 units.

Transforming the key points:

  • The maximum turning point (2,5)(-2, 5) on the original graph:

    • Horizontal shift: (23)=5(-2 - 3) = -5
    • Vertical shift: 5+2=75 + 2 = 7
    • New point: (5,7)(-5, 7)
  • The minimum turning point (3,1)(3, -1) on the original graph:

    • Horizontal shift: (33)=0(3 - 3) = 0
    • Vertical shift: 1+2=1-1 + 2 = 1
    • New point: (0,1)(0, 1)

Sketching the new graph:

The new graph will have:

  • A maximum turning point at (5,7)(-5, 7)
  • A minimum turning point at (0,1)(0, 1)

The overall shape remains the same as the original graph, but it's shifted to the left by 3 units and upwards by 2 units.

Would you like more details on sketching or have any questions?

Here are 5 relative questions to expand your understanding:

  1. How do horizontal and vertical shifts affect the derivative of a function?
  2. What happens to the symmetry of a graph after a transformation like f(x+3)+2f(x + 3) + 2?
  3. Can you explain how the turning points change after applying horizontal and vertical stretches or compressions?
  4. What is the effect of a negative coefficient on the function f(x)f(x), like f(x)f(-x)?
  5. How would the graph change if the transformation was y=f(x3)2y = f(x-3) - 2 instead?

Tip: When sketching transformations, always start by shifting key points like maximums, minimums, or intercepts to guide your drawing.
