Math Problem Statement

A logarithmic child function has domain of (-2, ∞). What is the range of the exponential child function that is its inverse?

A.(-2, ∞)

B.(2, ∞)

C.(-∞, -2)

D.(-∞, 2)

Solution

To solve this, we need to recognize that the logarithmic function and the exponential function are inverses of each other.

Given the domain of the logarithmic function is (2,)(-2, \infty), we know that the range of the exponential function (its inverse) will be the same as the domain of the logarithmic function, but in the context of an inverse, we must switch the domain and range between the two.

Thus, the range of the exponential function, which is the inverse, will be (2,)(-2, \infty).

Answer:

A. (-2, ∞)

Here are 5 related questions to expand on the topic:

  1. What is the general relationship between a function and its inverse in terms of domain and range?
  2. How do we derive the inverse of a logarithmic function?
  3. What are the key properties of logarithmic functions that affect their inverses?
  4. How does the base of a logarithmic or exponential function affect the domain and range?
  5. Can a logarithmic function have a negative domain?

Tip: Remember, for any function f(x)f(x) and its inverse f1(x)f^{-1}(x), the domain of f(x)f(x) becomes the range of f1(x)f^{-1}(x), and vice versa.
