#

i mean this was the first time i have come across this question

#

So you know about set builder notation?

agile spindle
#

i have not studied it at all

#

this was probably the question that we got in exams once in out of other questions

#

can you make it easier for me that what this question actually wants to know

#

like how to list the elements in situation like this when you dont have set r elements ure writing or listing them on your own like that

glad fern
#

This question wants you to list all the ordered pairs (x,y) where x belongs to set A and y belongs to set B and their corresponding z value(which can be obtained by using z=2x+y) and list all the values of z in a set

It only want you to list R itself, not the ordered pair (x,y). But couldn't hurt

okay thankyou

  • R = {z : z = 2x + y, x ∈ P, y ∈ Q}
  • R = {z : z = 2x + y, x ∈ {x : x = 0, 1, 2}, y ∈ {y : y = 0, 2}}
  • R = {z : z = 2x + y, x ∈ {0, 1, 2}, y ∈ {0, 2}}
  • R = {2x + y : x ∈ {0, 1, 2}, y ∈ {0, 2}}
  • R = {2x + 2k : x ∈ {0, 1, 2}, k ∈ {0, 1}}
  • R = {2(x + k) : x ∈ {0, 1, 2}, k ∈ {0, 1}}
  • R = {2(x + k) : x + k ∈ {0, 1, 2, 3}}
  • R = {2(x + k) : 2(x + k) ∈ {0, 2, 4, 6}}
  • R = {0, 2, 4, 6}
