Answer:

B represents a function.

Step-by-step explanation:

Recall these characteristics of a "function:"

Only one y-value can be associated with each x-value.  

Thus, A could not represent a function because there are two points with x = 1 and two different y-values:  (1, 1) and (1, -2).  

B represents a function because for each input (x-value) there is one and only one y-value associated.

C not a function:  (2, 3) and (2, -3) have two different y-values associated with one x-value (2).

D not a function:  (-3, 4) and (-3, -4) (see A and C, above)

The function w=30-3/4n represents the weight w in pounds of the papers in tyrones newspaper delivery bag after he delivers n new
adoni [48]

Answer:

domain (−∞,∞)

range (−∞,∞)

n = 40 and it refers to the fact that after delivering 40 newspapers, there will be no paper left in the bag

Step-by-step explanation:

To find the zero, we equate the linear equation to zero

w = 30 - 3n/4

3n/4 = 30

3n = 120

n = 120/3

n = 40

What this mean in this context is that the the bag becomes empty after he has delivered 40 newspapers or we can say that the maximum number of papers the bag can take is 40

The range refers to the number on the y-axis

Here the range is (−∞,∞)

The domain refers to the x axis values

We have (−∞,∞)
