Best ResponseYou've already chosen the best response.0discontinuity will occur when you have vertical asymptotes.. i.e., when one of the following happens 1. a division by zero i.e., denomiator becomes "0" 2. there is a possibility of having squareroot of a negative number.

Best ResponseYou've already chosen the best response.0set the denominator of the function to 0 \[(x6)(x5)=0\] solve for x

Best ResponseYou've already chosen the best response.0\[a\times b=0\] only if \(a=0\) or \(b=0\). so, \[x6=0\qquad x5=0\] get it?

Best ResponseYou've already chosen the best response.0just observe that if x=6 or x=5, the denominator becomes zero. We don't no what happens when you divide something by zero (some say you get a black hole, but whatever.) So, we just say we don't know what happens and don't mark that point on a graph. So, the graph will look like a rollercoaster track that's missing a piece of the track (Oh! the horror).
