Suppose that for a particular person enrolled in a typing class,
f(x)=55(x+1)/(x+8), for x greater than 0,
where f(x) is the number of words per minute the person is able to type after x weeks of lessons.
(A) What does f(x) approach as x increases?
(B) Sketch a graph of the function f, including any vertical or horizontal asymptotes.
This shows how to determine asymptotes and sketch a graph of a given situation.
