Yes it is a function because each domain has only one range means each x has only one y

Hope this helps!
23 is a prime number, so therefore the factors of it is just 1 and itself (23)
When x varies inversely with y then you'll have
xα1/y
x=k/y where k is the proportionality constant
when x=8. y=10. k=?
8=k/10
make k the subject of the formula
k=10×8
k=80.
When x=6. y=?.k=80
6=80/y
Make y the subject of the formula
y=80/6
y=40/3
