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 ...
