Math Problem Statement

The graph of y=f(x) is shown. Translate it to get the graph of y=f(x-5). The graph of y=g(x) is shown. Translate it to get the graph of y=g(x)-2.

Solution

This question involves translating the graphs of two functions.

Part (a): Translation of y=f(x)y = f(x)

The instruction says to translate the graph of y=f(x)y = f(x) to obtain the graph of y=f(x5)y = f(x - 5). This is a horizontal translation.

  • Translation Rule: For y=f(x5)y = f(x - 5), the graph of f(x)f(x) is shifted 5 units to the right.

Part (b): Translation of y=g(x)y = g(x)

The instruction says to translate the graph of y=g(x)y = g(x) to obtain the graph of y=g(x)2y = g(x) - 2. This is a vertical translation.

  • Translation Rule: For y=g(x)2y = g(x) - 2, the graph of g(x)g(x) is shifted 2 units downward.

Steps:

  • In Part (a), move the entire graph 5 units to the right.
  • In Part (b), move the entire graph 2 units down.

Here are some related questions to extend the concepts:

  1. How do horizontal and vertical translations affect the equations of functions?
  2. What is the difference between translating by xx units to the right and xx units to the left?
  3. Can translations change the shape of the graph, or only its position?
  4. How would you translate f(x)f(x) vertically by 3 units up instead of 2 units down?
  5. How does translating affect the domain and range of a function?

Tip: Always remember, shifting left or right modifies the xx-value inside the function, while shifting up or down affects the entire function result.
