Here's one piece of important information for this question: When a function touches the xaxis, that means that the value of the function f(x) = 0, so one of the factors (or more) must be zero. if f(x) = a(x) b(x) c(x)... then each unique value of x that makes at least one of the factors a zero must be a spot where the function crosses the axis.
