Using MATLAB ${?}^{o+}$ plot the function $f(x)=\frac{x^3-x^2+3x}{x^2-10x-200}$ for $-50x50.$ Notice that the function

has two vertical asymptotes. Plot the function by dividing the domain of $x$ into three parts: one

from $-50$ to the left asymptote at $x=-20,$ one between the left asymptote $x=20$ and the right

asymptote $x=10,$ and one from near the right asymptote to $50.$

Set the range of the $y$ axis from $-200$ to $200$ and use a solid line and different colours for each part of

the plot.
