Find h(t) + k(t) if h(t) = {(-4,5), (-2,-3), (0,5), (1,3), (3,-1), (5,5)} and

k(t) = {(-3,-2), (-2,6), (-1,0), (1,0), (2,-6), (3,5), (4,0), (6,-2)}. (2 marks)

h(t) = { (-4,5) ....} makes no sense to me

h(t) is a function of t
the right side is a SET
the operation + is not defined for sets

the operators for sets are AND, OR, NOT or complement
