Question

Do the sets R=(-∞, ∞) and R+= (0, ∞) have the same size/cardinality? Why or why not. Draw the bijection.

Answer 1

Answer:

Step-by-step explanation:

Countability Practice (a) No (0,1) and R+ do not have the same cardinality. For two sets to have the same cardinality, they must be bijection, which means they must be both onto and one-to-one.
