Provide an appropriate response.Suppose a friend tells you that the graph of f(x) = 
has a vertical asymptote with equation x = 4. Is this correct? If not, describe the behavior of the graph at 
A. This is incorrect. The graph has an oblique asymptote at x = 4.
B. This is incorrect. The graph is actually the graph of y = x - 4 with a "hole" at 
C. This is correct.
D. This is incorrect. The graph is actually the graph of y = x + 4 with a "hole" at (4, 8).
