The asymptotes of the function are given as follows:
The end behavior is that the function goes to y = 4 both when x goes to negative infinity and when it goes to positive infinity.
In this problem, the function is given by:
[tex]f(x) = \frac{4x}{x - 16}[/tex]
For the vertical asymptote, we have that:
x - 16 = 0 -> x = 16.
For the horizontal asymptote, we have that:
[tex]y = \lim_{x \rightarrow \infty} f(x) = \lim_{x \rightarrow \infty} \frac{4x}{x - 16} = \lim_{x \rightarrow \infty} \frac{4x}{x} = \lim_{x \rightarrow \infty} 4 = 4[/tex]
Hence the end behavior is that the function goes to y = 4 both when x goes to negative infinity and when it goes to positive infinity.
