Question

5.Oliver wants to make apple pie for the school event. He went to the orchard to buy apples, and he noticed small bugs on them after he returned home. The number of bugs grows at an exponential rate modeled by the function g(t)=10(3)t
, where g is the number of bugs after t days. Define an appropriate domain for the problem if Oliver bakes the apple pie 4 days after returning from the orchard(1 point)

2.The cost to rent a motorcycle includes a one-time refundable fee and the cost per day the motorcycle is rented. The total cost to rent a motorcycle for one or more days can be represented by the function C(n)=85n + 100
where n
represents the number of days the motorcycle is rented. What does the value 85 represent in this scenario?(1 point)

Answer 1

5. Domain for g(t)=10(3)^t if Oliver bakes 4 days after returning:
- {t | 0 ≤ t ≤ 4}

4. Which x would make the relation not a function?
- x = -4

3. Determine if each relation is a function:
- {(1,3), (2,3), (-8,3), (0,3)} — Function
- {(4,9), (-3,1), (6,3), (4,3), (7,14)} — Not a function
- {(3,2.5), (8,-1.4), (4.5,-10), (3,2.5), (1.2,1.8)} — Function
- {(0,0), (-1,1), (-2,2), (-3,3), (-4,4)} — Function

2. In C(n) = 85n + 100, what does 85 represent?
- 85 represents the cost per day the motorcycle is rented.

1. All valid representations for the domain (minutes spent studying in the last hour):
- {x | 0 ≤ x ≤ 60}
- [0, 60]
