Math Problem Statement
A function g(x) is defined by g(x) = -log4(x - 3) + 2. Part A: Graph the logarithmic function g(x) and determine the domain, range, and x-intercepts. Show all necessary calculations. Part B: Determine the vertical and horizontal asymptotes of g(x). Show all necessary calculations. Part C: Describe the interval(s) in which the graph of g(x) is positive. Determine the end behavior of g(x).
Solution
Let's break down the problem step by step. The function given is:
Part A: Graph the function, determine the domain, range, and x-intercepts.
-
Domain:
- The argument of the logarithm, , must be positive: Thus, the domain is:
-
Range:
- The base function has a range of .
- Adding shifts the range vertically by 2, so the range remains:
-
X-Intercept:
- To find the x-intercept, set : Rearrange: [ -\log_4(x - 3) = -2 \implies \log
