Is -6.743743… a rational or irrational number?
yaroslaw [1]

It's rational because it contains a repeating digit pattern, 743 (first option).

In particular, if

<em>x</em> = -6.743743…,

then

1000<em>x</em> = -6,743.743743… .

Subtracting, we can eliminate the trailing end and solve for <em>x</em> exactly:

1000<em>x</em> - <em>x</em> = -6,743.743743… - (-6.743743…)

999<em>x</em> = -6,737

<em>x</em> = -6,737/999

I really need someone to help me out
elixir [45]

All it takes for a relation to be a function is for each possible first number of a pair there's only one possible second number.


So if any of the sets has two pairs with the same first number, that one's not a function.


The last one has (3,2) and (3,5) so isn't a function.
