The second block (graphs and relations, mappings) 04 (1 point). For the mapping from the set A = {a1, 42, 43, as) to the set B - (b, babe represented with following assignments a {ba), aq[b, bs, bu), 839 (bz, bs) apbu) der the image of the set (a), A2, as) and the preimage of the set (bs, bs). Q5 (2 points). How many vertices and how many edges do W, graph has? Draw the example where n-6, 06 (3 points). Determine whether the given functions defined in the set of real numbers (geometrically depicted as the straight line of numbers) are bijections (if the decisions are not justified, the maximal assessment is 2 points): a) f(x) = -1 b) f(x) = x Place for answers
