document.write( "Usually, cross the straight through. However, there is more than one way that the polynomial can intercept the . There are actually    that the graph intercepts the . In the , it passes straight through no problem. In the  , it goes down and touches the and then rebounds off it. In the  , the graph sort of lingers around the interception point before crossing.\r

document.write( "Why are there three types of intercepts? This is governed by a mathematical thing called  . Multiplicity is the number of times a particular  or solution appears.

document.write( "2. If the intercept has an  multiplicity, meaning it occurs  , times,  times, etc., then the graph appears to touch the x-axis and then bounces off in the same direction it came from. The graph never passes through the x-axis, it simply touches it and goes back. As multiplicity increases, the valley will become flatter and flatter.\r

document.write( "3.If the has an  multiplicity, meaning it   ,  times, etc., then the graph kind of lingers around the interception point before passing through. The graph does actually pass through, but it is sort of delayed before actually passing through, like in the image. As multiplicity increases, the deflection becomes closer and closer to the .\r
