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.
Answer:
69
Step-by-step explanation:
so x2 will give you 9 times 7 which is 63. add it to 2 times 3 which is 63 + 6 will give you 69.
Positive integer factors of 100:
1, 2, 4, 5, 10, 20, 25, 50, 100
Now find if they are a multiple of 2 or 3.
2, 4, 10, 20, 50, 100
That is 6 factors.
