Supply chain integration a. includes its suppliers earlier into the design of new services or products. b. strives to work with its customers and suppliers. c. ensures that everyone benefits from improved flows of services, materials, and information. d. all of the above

D. All of the above

Step-by-step explanation:

To understand this question it is important to understand what is meant by Supply Chain and what is its scope.

Supply chain is a term that encompass the processes involved in the procurement of raw material from supplier and dispatching it to the customer. In a sense it covers most, if not all, aspects of the organisation.

Supply Chain Integration involves optimizing and aligning all process within in a supply chain, usually with a management or a software system. It improves communication and coordination with suppliers and customers and improves flow of materials

Hence the answer is D

the range of a function is the range of y-values for which it is defined, or exists. given that we are only looking at the y-values, we can already discount the first two answers as they deal with the domain of the function (range of x-values).

now, what we need to do is find the smallest and highest y-values for which the function is defined. if you'd like, you could take a ruler and start at the very bottom of the graph, find the lowest point, then move the ruler higher and higher until you reach the highest point. doing so either in your head or with an actual ruler, we can see that the lowest y-value is -5 and the highest y-value is -1.

the question now remains as to whether they are included in the range (fourth answer) or excluded (third answer). the key here is to recognise whether they are marked with an open or a closed circle. since both (-2, -5) and (2, -1) are marked with a closed circle, they are points that exist on the graph and are thus included in the range (note that if they were marked with an open circle like (4, -2) then that would signify that there is a break in the graph at that point).

thus, the fourth answer, (y | -5 ≤ y ≤ -1), is correct.

also note that usually it is good practice to scan your eye inbetween the highest and lowest point for any breaks in the graph - we do have one here at (4, -2), however -2 is still included in the range because there is another point that is included in the graph with the same y-value, ie. point (1, -2).

i hope that but if you require any further explanation don't hesitate to comment below.
