Question 1
R { 1,2,3,4 }
Z { 5,6,7,8 }
F is a subset of RZ
Where each element X ∈ R
and each element Y ∈ Z
(x, y) ∈ F
F subset { y ∈ Z| ( x, y) ∈ F for some x ∈ R}
R is the domain
Z is the codomain
, (4), ∈ Z
2.65 to 6.65
On the graph point 2.65 is (2.65, 4)
And point 6.65 is (6.65, 4)
x ∈ Z y ∈ R
( x, y ) ∈ F is a subset of RZ
Using = 4 Transforming R along itself
R ( 2.65, 4 )
F( 6.65, 4 )
R + Z defines a function since each element of R occurs only once among the ordered pairs.
Where set:
R is the ...
