Answer:
the bottom left one (the graph that looks like a circle) is not a function, but the other ones are.
Step-by-step explanation:
A function is defined so that for every x value within a function has a y value. This means that an x value CANNOT have more than one y value. The bottom right one has two y values for almost every x value within the domain. The top ones are functions, because all x values have only 1 y value (a discontinuous function is still a function!) And the bottom right is too.

Answer: 1) 8/15 2) 2 4/9 3) -13/45
Step-by-step explanation:
1/5 + 1/3 = 6/30 + 10/30 = 16/30 = 8/15
2 1/9 + 1/3 = 19/9 + 3/9 = 22/9 = 2 4/9
1/9 - 2/5 = 5/45 - 18/45 = -13/45
