Is the following relation a function? two ovals, one labeled x and the other labeled y. The negative 2 in the x oval is pointing to the 3 in the y oval, the 0 in x is pointing to 1 in y, 5 in x pointing to 8 in y, and 7 in x pointing to 5 in y
The answer is No. Because the 0 in x oval is pointing to BOTH 1 and 3 in y oval. And that must not happen in order to relation be a function. The following conditions must be satisfied for relation to be a function: 1. condition: EVERY element in the first oval has to be connected to some element in the second oval. 2. condition: Elements in the first oval MUST NOT have more than one connection with elements in the second oval.
