8. Given the following function 2x - 1 f ( x ) = x2 - 4 a) Identify all x intercepts b Y-intercept c) find all asymptotes (Vertical, Horizontal and Slant/Oblique). If one doesn't exist then state NONE for that Asymptote. [Remember you only will have a horizontal OR a slant asymptote but not both. Why? How do you know there are NO slant asymptotes? Rewrite the above function to make it have slant asymptotes instead of horizontal] d) Graph the rational function using the above information
