Math Problem Statement

Graph the parent function x ) g(x)=log 0.5 ​ (x)

Solution

The function you're asking to graph is g(x)=log0.5(x)g(x) = \log_{0.5}(x). This is a logarithmic function with a base of 0.5. The parent function for logarithms is generally logb(x)\log_b(x), where bb is the base.

Key Characteristics of g(x)=log0.5(x)g(x) = \log_{0.5}(x):

  1. Domain: The function is only defined for x>0x > 0.
  2. Range: The range is all real numbers (,)(-\infty, \infty).
  3. Intercept: It crosses the x-axis at x=1x = 1 because log0.5(1)=0\log_{0.5}(1) = 0.
  4. Asymptote: There is a vertical asymptote at x=0x = 0.
  5. Behavior: Since the base 0.50.5 is between 0 and 1, the function is decreasing. This means as xx increases, g(x)g(x) decreases.

I will now graph this function.It seems there was an issue generating the graph. I will try again.It seems the graph is still not generating correctly. I will describe the graph instead:

Description of the Graph:

  • Shape: The graph of g(x)=log0.5(x)g(x) = \log_{0.5}(x) starts high on the left (as xx approaches 0 from the positive side) and decreases as xx increases, curving downward as it approaches the x-axis.
  • Asymptote: The vertical asymptote at x=0x = 0 means the graph goes infinitely down as it gets closer to the y-axis from the right.
  • Intercept: The graph crosses the x-axis at x=1x = 1, since log0.5(1)=0\log_{0.5}(1) = 0.
  • Decreasing Nature: The graph decreases as xx increases because the base of the logarithm is between 0 and 1.

Tip:

When graphing logarithmic functions, always consider the base. Bases between 0 and 1 will yield decreasing functions, while bases greater than 1 will yield increasing functions.
