Please help as much as you can:
Q(t)= 700-400e^-(0.5)t
Does Q(t) have a relative max? relative min? inflection point?
Q'(t)= -200e^-(0.5)t=0 ( i am stuck)
5-) What is the absolute max and absolute min for the interval between zero and six.?
6-) draw a sketch of Q(t)
7-) What is the area under the sketch from t=0 to t=2?
8-) what is the average value of Q(t) between t=0 and t=2
9-) When going from t=0 to t=2, how much does the value of Q(t) change?
10-) If the graph of Q(t) were rotated around the "X" axis, it would create an volume could be expressed by what definite integral? (from t=
