Define a function.

State whether or not each of the following diagrams defines a function

Let A={x in R:- 1 = 0}and let S={(x,y)in A xx B: x^2+y^2=1} and S_0={(x,y)in A xx C: x^2+y^2=1}. The (A) S defines a function from A to B (B) S_0 defines a function from A to C (C) S_0 defines a function from A to B (D) S defines a function from A to C

Let A={x in R :-1lt=xlt=1}=B and C={x in R : xgeq0} and let S={(x ,\ y) in AxxB : x^2+y^2=1} and S_0={(x ,\ y) in AxxC : x^2+y^2=1}dot Then S defines a function from A to B (b) S_0 defines a function from A to C (c) S_0 defines a function from A to B (d) S defines a function from A to C
