Answer:
(a) It is a function.
(b) D = [1,2,3,4,5]
(c) R = [40,80,120,160,200]
Step-by-step explanation:
(a) Is this a function?
Yes, in order to be a function we need two groups, in this case "time in days" and "total cost". From this group the first one is called the domain, while the other one is called range. The elements in the domain can only have one associated element in the range. By this definition the graph displays a function.
(b) What is the domain?
The domain of a function are the numbers which represent the possible input. In this case it is the group of integer numbers from 1 to 5, in order words D = [1, 2, 3, 4, 5].
c) What is the range?
The range is the group which represent the output of the function and in this case it is the group R = [40, 80, 120, 160, 200]

Answer:
1 is less than or equal to x
1 ≤ x
<span>You are given the equation:
</span><span>(x - 3)/3 = x + 3
The first step to solving is getting rid of the denominator on the left-hand side of the equation. You get rid of denominators by multiplying both sides of the equation by the reciprocal. The denominator here is 3, so you'd multiply both sides of the equation by 3. That yields the equation in Step 1.

Since you are multiplying both sides of the equation by a quantity, you are using the Multiplication Property.
