Hi you guys, I definitely read the rules and I know it says not to post too many questions at once. But I have a final tomorrow and need your help and patience! I know you all could be doing anything else right now but if you can help I'd greatly appreciate any advice.

This problem involves graphing (see below)

The part of the problem that I highlighted sort of confused me. On that part I figured out the sign of f''(x) over the interval (-2, 1) but then wrote the opposite on the actual graph. It seemed to make sense when deciding whether that section of the graph should be convex/concave up/down.

I tried following the instructions and came up with this graph of f(x)

That was my attempt, it is supposed to follow this example of drawing a graph based on the signs of f'(x) and f''(x) over specified intervals.
