1. The problem statement, all variables and given/known data The question provides a graph and asks for the local minimums. I attached a picture with the graph. 2. The attempt at a solution I said the local minima are when x=0,2,5. However the answer key suggests they are at 1,2,5. Could someone please explain why 1 is a local minimum? It is just a point on the graph... Maybe the answer key is wrong.
