1,3 1,5 1,7 1,9 is this a function . what is the domain and the range
2 answers:
f(x) = {(1,3), (1,5), (1,7), (1,9)}
Domain = 1, 1, 1, 1
Range = 3, 5, 7, 9
No...this is not a function because a function cannot have any repeating x values. They can have repeating y values, just not the x ones.
The domain is all the x values { 1 }...if they are repeating, u only have to write it once.
The range is all the y values { 3,5,7,9}

Step-by-step explanation:
Let:
x=length
(x/4)+1=width
P=2l+2w
62=2x + 2[(x/4)+1]
62=2x + 1/2x + 2
multiply both sides by 2
124=4x+x+4
5×=120
x=24
length: 24 inches
width: 7 inches
