Ответ:
B
Step-by-step explanation:
h(t) = (t + 3)² + 5
A) h(t) = (t + 3)² + 5 -2 ≤ t ≤ 0
average rate of change in h over the change in t is given as:
It does not have a negative average rate of change
B) A) h(t) = (t + 3)² + 5 -4 ≤ t ≤ -3
average rate of change in h over the change in t is given as:
It have a negative average rate of change
c) A) h(t) = (t + 3)² + 5 -3 ≤ t ≤ 4
average rate of change in h over the change in t is given as:
It does not have a negative average rate of change
D) h(t) = (t + 3)² + 5 1 ≤ t ≤ 4
average rate of change in h over the change in t is given as:
It does not have a negative average rate of change
