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 :) </span>
If the fraction cannot be simplified any more, you can multiply both the numerator and denominator by an number.
5/6 (multiply the top and bottom by 2) is the same as 10/12 8/22 (can be simplified by dividing top and bottom by 2) is 4/11 25/30 (simplified by dividing by 5) is 5/6 5/15 (simplified by dividing by 5) is 1/3
