Math Problem Statement

Which of the following statements about the graph are true?

Solution

To analyze this question, let’s first examine the graph and the given statements. The graph seems to depict an exponential function or something similar, characterized by rapid growth for positive xx-values and an asymptote along the x-axis.

Here’s the breakdown of each statement:

  1. The range is y>0y > 0:
    This statement is true because the function only takes positive values; it never reaches or goes below y=0y = 0. The function approaches zero but does not cross it.

  2. The domain is x>0x > 0:
    This statement is false. The graph exists for all xx-values, not only for x>0x > 0. Therefore, the domain is not limited to positive xx-values.

  3. The domain is all real numbers:
    This statement is true because the function is defined for every real number on the x-axis.

  4. The asymptote is x=0x = 0:
    This statement is false. The graph has a horizontal asymptote at y=0y = 0, not a vertical one at x=0x = 0.

  5. The range is all real numbers:
    This statement is false. The range of the function is only positive values, meaning y>0y > 0.

  6. The asymptote is y=0y = 0:
    This statement is true as the function approaches but never touches or crosses the line y=0y = 0.

Summary of Correct Statements:

  • The range is y>0y > 0.
  • The domain is all real numbers.
  • The asymptote is y=0y = 0.

Let me know if you'd like further clarification on any of these points or more details on exponential functions!


Here are five related questions to further expand your understanding:

  1. How can you determine the domain and range of a function just by looking at its graph?
  2. What is an asymptote, and how does it affect the behavior of functions?
  3. What types of functions have horizontal asymptotes, and why?
  4. How would the graph change if the exponential function had a vertical shift?
  5. Can exponential functions have vertical asymptotes?

Tip: To identify the asymptote of a function, observe the line that the function approaches but never crosses or touches.
