Answer:
Min
Step-by-step explanation:
To check if it has a max or min, you must reference the a value. The a value in this case is 2, and that is positive. Positive parabolas point up, so they can only have a minimum point.
The 4 is the constant term.
1.679 kg * (40 min)/(kg) + 20 min = 67.16 min + 20 min = 87.16 min
I cant see the triangle so its kinda hard to know
