Final answer:
The horizontal asymptote of the function f(x) = 22 - 5 is a horizontal line at y = 17, making all provided answer options incorrect as none include this value.
Step-by-step explanation:
The question asks about the horizontal asymptote of a given function f(x) = 22 - 5. First, it is important to note that f(x) = 17 (since 22 - 5 = 17), which is a constant value and thus represents a horizontal line at the value of 17 on the y-axis. Therefore, the horizontal asymptote is the line y = 17, which would correspond to answer option c (22), if 22 had been the result of the function. However, in this case, there has been a mistake in the enumeration of the provided options, making all options incorrect.
