Let g(x) be a function where g(0)=0, g(2)=0 and g'(4)=0. Which of the following is a possible graph of g(x)? (I have attached an image of the graphs) First, I immediately eliminated choice C) because g(0) isnt 0. I dont really get what that little apostrophe means in g'(4)=0. Is that like the derivative? If someone can please explain this to me, Id appreciate it. thanks!
