The best way to approach this problem is to start off by doing factor by grouping.
Concave up is U-shaped.
There will be a inflection/critical point f'(x) =0 then a negative slope f'(x) = neg then another inflection/critical point f'(x) =0 at the bottom of the U-shape then a positive slope to last inflection/critical point. The interval for the Concave Up shape is the first and last inflection points.
I don’t know if you need to round, but you can do so on the answer for mondays if necessary
