which of the sets of ordered pairs represents a function?

a = {(2, −2), (5, −5), (−2, 2), (−5, 5)}
b = {(4, 2), (4, −2), (9, 3), (9, −3)}

only a
only b
both a and b
neither a nor b

Only A

Step-by-step explanation:

Let's remember the definition of a function:

A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

In A, each input has exactly one output so it's a function.

But in B, the inputs 4 and 9 have two different outputs, it can't represent a function.

The answer is only A.

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
