Plot the function f(x) = x2 + 3x – 5/x2 – 3x – 10 for -4 < x < 9. Notice that the function has two vertical asymptotes. Plot the function by dividing the domain of x into three parts: one from -4 to near the left asymptote, one between the two asymptotes, and one from near the right asymptote to 9. Set the range of they axis from -20 to 20.
