Problems from Logarithmic functions

Say if the following functions are increasing or decreasing:

  1. f(x)=log13⁡x
  2. f(x)=log23⁡x
  3. h(x)=log3⁡x
See development and solution

Development:

  1. The logarithmic functions are increasing if its base is greater than 1 and decreasing if a<1. Therefore the function is decreasing.
  2. Decreasing.
  3. Increasing.

Solution:

  1. Decreasing.
  2. Decreasing.
  3. Increasing.
