Question

List the ordered pairs in the relation R from A = {0, 1, 2, 3, 4} to B = {0, 1, 2, 3} where
(a, b) ϵ R if and only if a + b = 4.

Answer 1

do you understand what this means? for example
\((1,3)\) is in R since \(1+3=4\)

Answer 2

So basically I need to list the ordered pairs that would equal 4?

Answer 3

yes

Answer 4

easy right? that is why my first question was "do you understand what this means?"

Answer 5

I'm not really great in math and I've been looking for what the e symbol means to better understand it... but after your example, yeah its really easy. Thanks so much!

Answer 6

(1, 3), (2, 2), (3, 1), (4, 0) so this should be my answer
