The given function has no undefined points nor domain constraint. Thus, the domain is: 
.
<h3>Domain and Range</h3>
The domain of a function is the set of input values for which the function is real and defined. In the other words, when you define the domain, you are indicating for which values x the function is real and defined. An example, there is a restriction for the domain of fractions. The variable x in the denominator should be different of zero.
While the domain is related to the values of x, the range is related to the possible values of y that the function can have.
In this question, the function 
has no undefined points nor domain constraint. Therefore, the domain is:

Answer:
Hi the answer is this question has no answer xd
Step-by-step explanation:
Ok THIS QUESTION HAS NO ANSWER
Perimeter= 2(length+width)
60= 2(l+w)
l=2w
Substitution method
60= 2(2w+w)
60= 2(3w)
30= 3w
10= w
Plug the value of w in.
l= 2(10)
l=20
Final answer: Length= 20, width=10
(11)
we are given two points
(x1,y1)=(0,3)
(x2,y2)=(8,7)
so, we get
(a)
we know that slope of parallel lines are always equal
so, we can use formula
now, we can plug values
............Answer
(b)
we know that slope of perpendicular line is -1/m
so,
now, we can plug value
...............Answer
(12)
we are given two points
(x1,y1)=(5,-1)
(x2,y2)=(3,1)
so, we get
(a)
we know that slope of parallel lines are always equal
so, we can use formula
now, we can plug values
............Answer
(b)
we know that slope of perpendicular line is -1/m
so,
now, we can plug value
...............Answer
Y= (-4,0)
X= (0,2)
hopefully this helps
