Answer:
All positive real numbers
Step-by-step explanation:
Given
The model can be represented as:
Required
Determine the domain
This means that we list out possible values of x.
If x represents time, then it is impossible for x to be negative.
This implies that x can take any value as long as it is greater than or equal to 0.
<em>Hence, the domain is all positive real numbers</em>
To solve this problem you must apply the proccedure shown below:
1. You have that the ratio of the measures of the three angles is
2. The sum of the interior angle of a triangle is
3. Let's say that the measure of each angle is multiplied by the ratio. Therefore, you can write the following equation and solve for
:
4. Therefore, the measure of each angle is:
The answer is:
Answer:
D. (-2,-5), (0, -7), (1, -4)
Step-by-step explanation:
From Function Theory we must remember that range of a function is the set of images related to elements of the domain. In this case, we must find the image of each of the three elements that forms the domain of , which are:
,
and
.
Then we proceed to find all elements of range:
Which corresponds to option D.
