Step-by-step explanation:

No this is not proportional , because the ratio of y/x for each one is not same ,

As for 1st one ,

y/x =4/2 =2

for 2nd one ,

y/x=16/4 = 4 and so on

so they re not equal that's why they are not proportional

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
