Domains: 7, -7, 1, 3
Ranges: 3, -5, -2, -9
It is a function because all of the domains are different numbers. If they were the same then this would not be a function.
I think the answer is (C. 25/24). Sorry if this does not help.
Answer:
The fourth listed answer:
Domain: All Real numbers
Range : { f{x) | f(x) 
0, f(x) = 1 }
Step-by-step explanation:
The domain consists of all Real numbers (notice that you have a well defined f(x) value for all possible x on the horizontal axis.
The Range is associated with the set of those f(x) values (on the vertical axis) that are connected via the functional relationship with a value "x" of the domain. The line with positive slope extends to all f(x) values that are 0 (smaller than or equal to zero). While the flat horizontal line on the right of the plot corresponds to the line f(x) =1 (only one value of f(x) [1} connects with the x-values of the Domain that are larger than 3.

<h3>What is Ratio ?</h3>
Ratio is when a number is divided by any other number and written in the form p:q.
It is given in the question that
A commercial airplane broke a record when it traveled 5,540 kilometers from new york to london in 5 hours .
a different airplane traveled 2,964 kilometers from denver to hartford in 3 hours.
The airplane travelled 5,540 kilometers in 5 hours
In 1 hour , the commercial airplane covered 5540/5 = 1108 km.
In 1 hour , the other airplane covered 2964/5 = 592.8 km
Therefore the plane from new york to london fly 1108- 592.8 = 515.2 km per hour compared to the plane from denver to hartford .

(E) "cast doubt on the aptness of a description"
Writers will occasionally include a term or phrase in quotation marks to question its veracity. The author of paragraph 2 denigrates the learning theorists by putting the word "experts" in quotation marks because of their "shocking" estimate of canine intelligence.
The answer is not (A). One may contend that the author's use of quote marks conveys surprise or even irritation. (B) is the wrong answer. The term "experts" being surrounded by quotation marks is not a show of "respect," but rather of suspicion.
The answer is not (C). There is no need to doubt the plain usage of the word "experts" in this context, even when the author may have reservations about the theories of the experts. D is likewise a poor choice.
