<h3>How to determine the graph?</h3>Based on the information provided about this company with respect to its delivery and total number of miles to be covered, we would assign variables as follows:
- Let y represent same-day delivery.
- Let x be the total number of miles.
Next, we would translate the word problem into an algebraic equation by using an inequality:
y > x/2 - 3
Also, we would determine the intercepts as follows:
When x = 0, we have;
y = 0/2 - 3
y = -3.
y-intercept = (0, -3).
For the x-intercept, we have:
When y = 0, we have;
0 = x/2 - 3
x/2 = 3
x = 6.
x-intercept = (6, 0).

Answer:
- The domain of
is : {student}
- The range of
Step-by-step explanation:
Here are important things for a relationship to be a function:
- Every element in X is related to some element in Y.
- A function cannot have one-to-many relationship.
- A function must contain single valued
In the giving diagram of the question, it is clear that:
- Each student corresponds to one element of the range: High Test Score or Low Test Score.
Therefore, is a function.
As domain of a function is the set of all the x-values of a ordered pair.
So,
The domain of is : {student}
And range of a function is the set of all the y-values of a ordered pair.
So,
The range of is : {High Test Score, Low Test Score}
Therefore, from the above discussion 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.
