Answer:
- f(5), t=5 Minutes.
- f(60), t=60 Minutes
Explanation:
f(t) is the temperature of the yam t minutes after it is placed in the oven.
- In f(5), t=5 Minutes, therefore f(5) is the temperature of the yam 5 minutes after it is placed in the oven. At f(5), the yam is still in the oven since it is not yet up to 45 Minutes.
- In f(60), t=60 Minutes, therefore f(60) is the temperature of the yam 60 minutes after it is placed in the oven. Since the yam is taken out after 45 minutes, at f(60), the yam is no longer in the oven.
