find the local minimum value of the function f(x)=3+lxl, x is in R

What did you see when you graphed this function?

this may help, see the graph as suggested . . . . just DOUBLE CLICK the picture, it will enlarge

Says who? If that's the case, then perhaps you should say how you are allowed to solve it. We're not mind readers.

Drawing a graph is not difficult and is the recommended way for solving the problem.

I am +65. What's age go to do with it?

Okay, without a graph, what is the minimum value of |x|?

thanks for helping me
