State the domain and the range i'm overthinking it so idk plz !

So the domain is the list of x, or input, values in an relation. They are the numbers that the arrows start at. In this case, the domain is {4,16}.

The range is the list of y, or output, values in an relation. They are the numbers that the arrows are pointing at. In this case, the range is {4,-2,2}.

Now for a relation to be a function, every input must only have 1 output. In this case, this relation is not a function because when x = 4, y = -2 and 2.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
