I need the graph pleaeeee

Consider the function $f(x)=\frac{(15x^2+(5n-3m)x-nm)}{x^2+(n-m)x-nm},$

$n=2m=54$

Define your constant $m$ and $n.$

Declare your variable $x($as your symbolic variable with Matlab$).$

Define the function $($as inline function with Matlab$).$

Find the following limits by using Matlab $\underset{x-3\mathrm{.}75}{lim}f(x)$

Find the horizontal asymptote for the function $f(x).$

Find the vertical asymptotes for the function $f(x).$

Find the first derivative $f^{\text{'}}(x).$

Find the second derivative $f^{\text{'}\text{'}}(x).$

Find the critical points of the function $($using Matlab, solve for $f^{\text{'}}(x)=0)$

Plot the function with its first derivative on one plot, domain $-20,20.$
