Answer:
Second option!
Step-by-step explanation:
The x is -2, and as you can see the first one is at a positive 2, so the second one is the way to go.
Answer:
D=[0, 8 214.29]
R=[0, 230 000]
Step-by-step explanation:
In order to find the domain, we must think of the least price you can give to the product you are selling. The price cannot be less than zero, since that would mean that you are giving money to the consumer for taking the product away, so zero is the smallest value p can get.
The greatest value the price can get is the one such that the quantity demanded is zero. So we need to determine that price by setting the equation equal to zero and solving for p.
230,000-28p=0
so we get
-28p=-230,000

so
p=$8,214.29
so the restricted domain for this function would be:

or in interval notation:
D=[0, 8 214.29]
In order to find the range, we just need to determine what's the least and greatest value the function can get. Since this is a linear function, we can find them by just substituting each of the extreme values of the domain in the function, so we get:
q=230,000-28(0)=230,000
q=230,000-28(8214.29)=0
so the range would be:

or in interval notation:
R=[0, 230 000]
Answer:
numer 2
Step-by-step explanation:
Answer: D
Step-by-step explanation: On the first part, if it decreases by 17% each year, that means its value is 83% of what it was. You forgot to say that the car was bought 2 years ago.
Thus, the answer is D
For the second, just use the same logic to get 18000*0.75^4
Answer:
D
Step-by-step explanation:
-18 - 36n = -6(3 + 6n).
Use distributive property.
-6(3 + 6n)
-18 + (-36n)
-18 - 36n
-18 - 36n = -18 - 36n
Have a nice day!
