I’d say it’s between B and D
The domain of a function is the set of values of x in which the function can be calculated.
The range of a function is the associated values of the function respect to the domain.
You have the following function:

In order to determine the domain and range of the previous function, you consider that the given function is available for any value of x. Then, you have:
dom y: -∞ ≤ x ≤ ∞ : (-∞,∞)
The range of the function can be determine by noticing, on the graph, that the maximum value of the function is y=3 and also you can notice that there is no a limit for negatives values of the function. Then, you have:
ran y: -∞ ≤ y ≤ 3 : (-∞,3]
Answer:
So, the probability is P=0.041.
Step-by-step explanation:
We know that 45% of people in Fast-Food restaurants order a diet drink with their lunch.
We conclude that the probaility p=0.45 that a person order a diet drink.
We calculate the probability that the fourth person orders a diet drink.
We get:

So, the probability is P=0.041.
Answer: The expression simplified is this 2.25x-10.4
