Answer:
is a function because each student, or each element of the domain of the function corresponds to one element of the range.
Step-by-step explanation:
Here are some of the important factors for a relationship to be a function.
As we know that a function is a relation between sets that associates to every element of a first set exactly one element of the second set.
In the giving diagram of the question, it is clearly observable that:
- Each student in Mr. Well's history class associates to one Final exam score.
Therefore, is a function.
We know that the domain of a function is the set of all the x-values of an ordered pair of a set for which the function is defined.
Here,
The domain of is : {Student}
And range of a function is the set of all the y-values of a ordered pair of a set.
So,
The range of is : {Final Exam Score}
Hence, we conclude that is a function because each student, or each element of the domain of the function corresponds to one element of the range.
Answer:
-1/3
Step-by-step explanatition
the slope goes down to the right, so it is negitive. It goes down x by 3, and down y by 1. slope = y/x , slope = -1/3
Answer:
\/
Step-by-step explanation:
Let x = number of half-gallons the store bought
(x-15) is the number of half-gallons the store sold
Profit = Income - Cost
$65.72 = (x-15)*3.96 - (x)2.60
65.72= 3.96x - 59.40 - 2.60x [distribute]
125.12 = 1.36x [collect terms]
92 = x
