Yes, each value of x has one and only one value y.

YES aS LONG AS there are no x values repeated. Another way to tell if its a function is by graphing it and performing the vertical line test. After its graphed take a ruler or any straight vertical line and run it over the graph , if you do not hit more than a single point at any one time its a function.

Yes.
A relation would be a function if all the x values have a unique image(y value)
Therefore, this relation is a function.

Yes. If in doubt, plot these points on a graph and then imagine a vertical line passing throigh the points . . . if the vertical line only passes through one of the points at a given time as it sweeps over the domain, then you have a function, since that implies that all values of x produce only one value for f(x).

Consider it as a subset (R) of A X B where A={1,2,3,4,5,6,7,8} & B ={ 0,4,5,8,9}(say)
now by the definition of a function , here xRy for a unique y where x =1,3,4,7(elements belong to A).
Hence R is a function.

Yes thats a function

Look at your X values. If any of them repeat then you DO NOT have a function.

yes. all x's have different values; there are no repeated x values.
