Math Problem Statement

First vertically compressing the graph y = f(x) by a factor of 1/3 then shifting down 2 units gives the same result as shifting the graph of y = f(x) down 2 units then vertically compressing by a factor of 1/3.

Solution

The statement asks you to compare two transformations of the function y=f(x)y = f(x):

  1. First transformation: Vertically compress the graph of y=f(x)y = f(x) by a factor of 13\frac{1}{3}, then shift the graph down by 2 units.

    This would result in the equation: y=13f(x)2y = \frac{1}{3} f(x) - 2

  2. Second transformation: Shift the graph y=f(x)y = f(x) down by 2 units first, then vertically compress it by a factor of 13\frac{1}{3}.

    This would result in the equation: y=13(f(x)2)=13f(x)23y = \frac{1}{3} (f(x) - 2) = \frac{1}{3} f(x) - \frac{2}{3}

Comparing the results of these transformations:

  • The first transformation results in y=13f(x)2y = \frac{1}{3} f(x) - 2.
  • The second transformation results in y=13f(x)23y = \frac{1}{3} f(x) - \frac{2}{3}.

These two transformations do not give the same result, as the constants 2-2 and 23-\frac{2}{3} are different. Therefore, the statement is false.

  2. What is the difference between vertical compression and vertical stretching?
  3. How does the order of transformations affect the final graph of a function?
  4. Can you explain how reflecting a graph across the x-axis works?
  5. What is the effect of horizontally compressing a graph by a factor?

Tip: Always remember that the order of transformations, especially when involving shifts and compressions or stretches, can affect the outcome!
