Answer:

a. Function.

b. Function

c. Not a function.

d. Function.

Step-by-step explanation:

A function is a one-to-one or many-to-one relation NOT a one-to-many.

Choice c is not a function because 5 maps to -8 and to 5  ( we have (5, -8) and (5, 5)).

At first I wasn't sure about d. because of the 2  'x values' of -2. But the ordered pairs are the same so it is a function.
