Here they say there is a local max at 1: image image

But the graph is decreasing then decreasing at 1 so it can't be a local max.

It is definitely a local maximum. For instance, it's the highest point on the interval (0,2). It sounds like you're trying to use the first derivative test when it doesn't apply.

yes. I was going by the rules not the intuitive way of thinking of local max.
