Tell whether the relation is a function. Explain.

It is not a function.

Step-by-step explanation:

A relation can only be a function if every input (x-value) of the set of values of the relation, has exactly one output (y-value).

In the relation given, one input, -2, has two output related to it, 5 and 0. That's (-2, 5) and (-2, 0).

Therefore, the relation is not a function.

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
