(a) $A \cap B=\{0, 1, 5 \}$ (b) $A \cup B=\{-2, 0, \frac{1}{2},1, 3, 5, 7\}$

Work Step by Step

(a) We find the intersection by finding terms common to both A and B: $A \cap B=\{0, 1, 5 \}$ (b) We find the union by combining terms and removing duplicates: $A \cup B=\{-2, 0, \frac{1}{2},1, 3, 5, 7\}$
