Just add the rows from the top to the bottom
B, short explanation remember the sets are set up like (x,y) in a set there should be no matching x points so if it matches it's not a function :)
long explanation: these are (x,y) sets {(0,3), (3,0), (0,4), (4,0)} the first choice shows that there are two X solutions <span>if they are equal to 0 (0,3) (0,4) so this cant be a function.
second choice</span><span> {(0,2), (2,0), (4,6), (6,4)} does not have two X solutions so this is a function
third choice</span>{(2,6), (3,6), (4,6), (2,0)} has two X solutions if x is equal to 2
and the last choice <span>{(6,2), (2,0), (4,6), (6,4)} has two X solutions if x is equal to 6
hope i helped! if i did please give me brainlest :)

Answer:
volume of empty space = 141.3 cm³
Step-by-step explanation:
volume of empty space = volume of the cylinder - volume of water
First, we need to calculate the volume of the container
volume of a cylinder = πr²h
where r = radius of the container and h is the height of the container
r = 3cm and h = 12 cm π is a constant which is ≈ 3.14
volume of a cylinder = πr²h
=3.14 × 3²×12
=3.14×9×12
=339.12 cm³
We will proceed to find the volume of water
since liquid will take the shape of its container,
then volume of water = πr²h
r is the radius of the container and h is the height of the water
r = 3cm and h = 7cm
volume of water = πr²h
= 3.14 ×3²×7
=3.14×9×7
=197.82 cm³
volume of empty space = volume of the cylinder - volume of water
=339.12 cm³ - 197.82 cm³
= 141.3 cm³
OR
WE CAN SOLVE DIRECTLY
height of empty space = height of container - height of water
= 12 - 7
=5 cm
volume of empty space = πr²h
=3.14×3²×5
=3.14×9×5
=141.3 cm³
volume of empty space = 141.3 cm³
