Let be a surjective continuous map between topological spaces. Show that:

a) If f is an identification mp, then for any pace Z and any map the composition is continuous if and only if g is continuous.
b) If, for any space Z and any map , the composition is continuous if and only if g is continuous, then f is an identification map.

    If instead we have a relation g: {1, 2, 3} -> {1, 4, 6, 7}, which simultaneously maps g(2) = 4 and g(2) = 6 (and keeps g(1) = 1, g(3) = 7), then g is not a valid mapping. X and Y can also be continuous. For example, let X be the entire real line.
