Please help with this question:

D Question 1 1 pts Given two sets A and B. Which of the rules below define a function f : A - B? O A = { all points in the plane } , B = {all circles in the plane }, to each x we assign a circle f (x) with radius 1 and center x. Q A = [-1, 1], B = R, to each x from A we assign y from B satisfying | x| + ly| = 1. ( A = {all English words), B = NU {0), to each w in A we assign f(w), the number of vowels in w. Q A = B = Z, to each m from A we assign n from Bsuch that mn = 1. ( A = {all countries ) , B = {all cities }, to each country x we assign its capital f(x).D Question 2 1 pts O Choose a function whose graph is shown in the picture: f : N - R, f ( x ) = *+ x/ 2 Oh : Z - 2, h(t ) = t+ |+1 Or : Z - 2, r ( k ) = [kl - k 2 O g : Z - R, g(m) = m + ml 2
