Math Problem Statement

Transform the graph of y = e^x to the graph of y = e^(x-5) + 3. Give the domain and range using interval notation.

Solution

Let's break down the tasks required based on the image.

  1. Transformation of the graph of y=exy = e^x to y=ex5+3y = e^{x-5} + 3:

    • Start with the base graph y=exy = e^x, which is an exponential function.
    • The transformation involves two steps:
      • Horizontal shift: The x5x-5 indicates a horizontal shift to the right by 5 units.
      • Vertical shift: The +3+3 means a vertical shift upwards by 3 units.
  2. Domain and Range of y=ex5+3y = e^{x-5} + 3:

    • Domain: The domain of the exponential function is all real numbers (,)(-\infty, \infty), since the exponential function is defined for all real values of xx.
    • Range: The range of the base function y=exy = e^x is (0,)(0, \infty). After the vertical shift by 3, the range becomes (3,)(3, \infty), because the lowest point of the graph will now be shifted from 0 to 3.

So, in interval notation:

  • Domain: (,)(-\infty, \infty)
  • Range: (3,)(3, \infty)

Here are 5 related questions to explore further:

  1. How does the horizontal shift affect the asymptote of an exponential function?
  2. How would the graph change if the function was y=e(x5)+3y = e^{-(x-5)} + 3?
  3. What is the behavior of the function as xx \to -\infty and xx \to \infty?
  4. How would you reflect the graph of y=ex5+3y = e^{x-5} + 3 across the x-axis?
  5. What would the domain and range be if the transformation were y=ex53y = e^{x-5} - 3?

Tip: When transforming graphs, horizontal shifts are typically inside the function's exponent or argument, while vertical shifts are added or subtracted outside.
