Question 999751
These are not steps of arithmetic, but are just adjustments in the process of matching the specifications for the function:

<pre>
{{{y=k(x)/x}}}           degree of numerator and denominator be same

{{{y=2x/x}}}             want value of 2 to be approached at extreme x values

{{{y=2x/(x-3)}}}         must be undefined at x=3

{{{highlight(y=2(x+5)/(x-3))}}}     x-intercept of -5
</pre>
