A store is having a sale on apples, but won’t allow you to buy more than 5 pounds. Use interval notation to write the domain and range of the function C(x)=2.49x, where x is the weight of the apples (in pounds) and C(x) is the cost (in dollars)

The cost of x pounds of apples is given by the equation:

C(x) = $2.49*x

Where the domain is the set of the possible values of x and the range is the set of the possible values of C(x)

We want to find the range of possible prices that you can pay.

The minimum number of pounds of apples that you can buy is 0 (this represents the case where you do not buy apples).

C(0) = $2.49*0 = $0

The maximum value for x is x = 5

Replacing that value in our equation we will find the maximum possible cost:

C(5) = $2.49*5 = $12.45

Then the domain is: D : [0, 5]

The range is:             R = [$0, $12,45]

Notice that here i used the symbols [], this is because the the values in the extremes are allowed values in the domain and in the range.

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.

step-by-step explanation: just trying to get points sorry : (

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
