Question 1111201
.
<pre>
If f(x) = {{{(x+8)/(2x-8)}}},  then


the domain is the set of all real numbers except of x = 4.


In the interval notation,  the domain = ({{{-infinity}}},{{{4}}}) U ({{{4}}},{{{infinity}}}).


It is the same as to say that the domain is the entire number line with the hole at x= 4.

Next time, when you post formulas to the forum, use parentheses to point which part is the numerator and which is the denominator.
