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.
32.92 next is 27 last is 230
35%.
42/120 = 0.35.
0.35 X 100 = 35. That tells us 42 is 35% of 120.
