Math Problem Statement

How do you transform the graph of y = 3^x to become the graph of y = 3^(x-4) + 2?

Solution

The question asks how to transform the graph of y=3xy = 3^x to become the graph of y=3x4+2y = 3^{x-4} + 2. Let me break this down step by step:

  1. Horizontal Shift:

    • The term x4x-4 in y=3x4+2y = 3^{x-4} + 2 shifts the graph of y=3xy = 3^x 4 units to the right.
  2. Vertical Shift:

    • The +2+2 outside the exponent causes a vertical shift, moving the graph 2 units up.

Transformation Instructions:

  • Start with the graph of y=3xy = 3^x.
  • Shift the graph 4 units to the right.
  • Then, shift the resulting graph 2 units up.

Here are five related questions to expand your understanding:

  1. What happens to the graph of y=3xy = 3^x if the equation becomes y=3x+31y = 3^{x+3} - 1?
  2. How do horizontal and vertical shifts affect the asymptote of an exponential function?
  3. How do you determine the direction of a shift from the equation of a function?
  4. How do transformations like y=3xy = 3^{-x} and y=3x+5y = 3^{x} + 5 combine multiple effects?
  5. What are the graphical differences between y=3xy = 3^x and y=2xy = 2^x?

Tip: Remember, transformations do not change the shape of the graph, just its position!
