Answer:
Yes
Step-by-step explanation:
Any relation is said to be a function , if and only if
i) every element of first ordered pair is mapped with some element of second ordered pair.
ii) every element in first ordered pair is mapped to only singe element from the ordered pair.
Here in this case we see that there is some value of y for every value of x Hence first condition satisfies.
Also , none of the value of x is mapped or resulting into a two different values of y
Hence both the conditions are fulfilled , there for it is a function.
