Consider the given rational function and find vertical asymptotes and values of x corresponding to holes(if applicable). 

f(x) = (x² -49)/(x +7)

For the following function, write the equation for the vertical asymptote.

f(x) = (x + 8)/(x + 11)

For the following rational function, graph. f(x) = 5x/(x² - x - 12)
