Question 4: Let the function y=f(x) be continuous on and have a graph as shown in the figure. How many extreme points does the graph of the function \(y=|f(|x|)|\) have in all?

From the graph of the function y=f(x), we have the graph of the function \(y=f(|x|)\)

From the graph of the function \(y=f(|x|)\) we have the graph of the function \(y=|f(|x|)|\)

Derive the graph of the function \(y=|f(|x|)|\) There are 7 extreme points.
