Is this a function? there is two answer choices i am
confused on, so i just want to know if this is right.

Yes, its a function.

Step-by-step explanation:

The vertical line test is a great way to determine if something is a function. If you can draw a line and it doesn't pass through multiple points, its a function. All parabolas facing straight up or down are functions.

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.
