Answer: The below figure shows the graph of the given situation.
Step-by-step explanation:
Since, at first Caroline has brownies= 48
And, according to the question, it is decreasing by 6 per hour.
Then, the function of the given situation can be written as,
f(x)=48 - 6 x, ------ (1)
where, x is the number of hours and f(x) is the number of brownies Caroline has left in x hour.
Thus by substitution x= 0,1,2,3,4,5,6,7,8 in equation (1),
We get, f(x)=48, 42, 36, 30, 24, 18, 12, 6, 0
So, the function has points, (0, 48), (1, 42), (2, 36), (3, 30), (4, 24), (5,18 ),(6,12 ) (7, 6) (8, 0).
With help of the above points we can draw the graph of the given situation.
Note: since at x=8, f(x)=0 therefore after 8 hours she has no brownies left.
