Ответ:
Yes.
Step-by-step explanation:
Yes.
To have a function, you cannot use the same value for an x-coordinate more than once. Here, each value of an x-coordinate is used only once, so it is a function.
Ответ:
Yes.
Step-by-step explanation:
It is a many-to-one function. Both 3 and 1 map to 8.
2 maps to to 3 and -1 maps to 4 which is one-to-one.
There are no one to many mappings so it is a function.
