This is a a reflective property because it is an if then statement.
Reqires the lines to have the same slope
the domain of the following graph= [-5,10)
Domain :
The domain of a function is the set of its possible inputs, i.e., the set of input values where for which the function is defined. In the function machine metaphor, the domain is the set of objects that the machine will accept as inputs.
For example, when we use the function notation f: R→R, we mean that f is a function from the real numbers to the real numbers. In other words, the domain of f is the set of real numbers R (and its set of possible outputs or codomain is also the set of real numbers R).
To, identify the domain and range of functions by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the
x-axis. The range is the set of possible output values, which are shown on the
y-axis. Keep in mind that if the graph continues beyond the portion of the graph we can see, the domain and range may be greater than the visible values.
We can observe that the horizontal extent of the graph is -5 to 10, so the domain of f is [-5,10)

The number of cruise passengers must there have been in 2017 is 26.7 million.
<h3>What is percentage?</h3>
The term "percentage" comes from the Latin phrase "per centum," meaning "by the hundred." Percentages represent fractions with a denominator of 100. In other terms, it is the relationship between portion and whole in which the value of the whole is always assumed to be 100.
Now according to the question;
Let x represent the total number for cruise passengers during 2017.
In 2018, a 6.7% rise in x results in 28.5 million cruise passengers.
So, 106.7 % of x = 28.5
![\begin{aligned}&\frac{106.7}{100} * x=28.5 \\&\frac{106.7 x}{100}=28.5\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7D%26%5Cfrac%7B106.7%7D%7B100%7D%20%2A%20x%3D28.5%20%5C%5C%26%5Cfrac%7B106.7%20x%7D%7B100%7D%3D28.5%5Cend%7Baligned%7D)
Multiplying both sides by 100;
![\begin{aligned}&\frac{106.7 x}{100} * 100=28.5 * 100 \\&106.7 x=2850\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7D%26%5Cfrac%7B106.7%20x%7D%7B100%7D%20%2A%20100%3D28.5%20%2A%20100%20%5C%5C%26106.7%20x%3D2850%5Cend%7Baligned%7D)
Dividing both sides by 106.7;
![\frac{106.7 x}{106.7}=\frac{2850}{106.7}](https://tex.z-dn.net/?f=%5Cfrac%7B106.7%20x%7D%7B106.7%7D%3D%5Cfrac%7B2850%7D%7B106.7%7D)
x = 26.7
Therefore, the number of cruise passengers in 2017 must have ranged from 26.7 million.
