#2**+2 **

Here are the characteristics of roots :

(1) Any root of an even multiplicity means that the graph will be tangent to the x axis at this root

(2) Any root of a multiplicity of 1 means that the graph will cross the x axis at that root

(3) Any root of an odd multiplicity > 1 means that the graph will "hug" and cross the x axis at that root

So.....

It wil cross the x axis at the roots 2 and 4

It will be tangent to the x axis at the root of 1

At root 6, the graph will cross through while hugging
