Math Problem Statement

Given the graph of the function y=f(x), sketch the graph of each transformed function: a) y-3=f(x), b) h(x)=f(x+1), c) y+1=f(x-2). Describe how to translate the graph of y=|x| to obtain the graph of the function shown, and write the equation of the transformed function in the form y-k=|x-h|.

Solution

Let's go through the questions in the image step by step:

1. Given the graph of the function y=f(x)y = f(x), sketch the graph of each transformed function:

  • (a) y3=f(x)y - 3 = f(x):

    • This transformation represents a vertical shift. Since y3=f(x)y - 3 = f(x), we can rewrite it as y=f(x)+3y = f(x) + 3. This means the graph of f(x)f(x) is shifted up by 3 units.
  • (b) h(x)=f(x+1)h(x) = f(x + 1):

    • This transformation represents a horizontal shift. f(x+1)f(x + 1) shifts the graph left by 1 unit (since the transformation is inside the function, it affects the graph in the opposite direction).
  • (c) y+1=f(x2)y + 1 = f(x - 2):

    • This can be rewritten as y=f(x2)1y = f(x - 2) - 1. It involves two transformations:
      • A horizontal shift right by 2 units (since x2x - 2).
      • A vertical shift down by 1 unit (due to 1-1).

2. Describe how to translate the graph of y=xy = |x| to obtain the graph of the function shown:

  • The graph given is a transformation of y=xy = |x|, a basic "V" shape.
  • It appears to be shifted right by 4 units and down by 2 units.
  • The equation for this transformation in the form yk=xhy - k = |x - h| would be: y+2=x4y + 2 = |x - 4| Or equivalently: y=x42y = |x - 4| - 2

Let me know if you'd like further clarifications or more details on these transformations!

Here are 5 related questions to explore further:

  1. How do vertical stretches or compressions affect the graph of a function?
  2. How would the graph of y=f(x)y = f(x) change if the equation were y=f(x)y = -f(x)?
  3. What does y=f(x)y = f(-x) do to the graph of f(x)f(x)?
  4. How do you apply a reflection over the x-axis to a function?
  5. How does adding a constant inside the absolute value (e.g., x+3|x + 3|) affect the graph?

Tip:

Always check whether the transformation is inside or outside the function to determine whether it affects the graph horizontally or vertically.
