#MADE NOTE

Question

F={AB$\rightarrow$C,A$\rightarrow$C}

G={A$\rightarrow$C}   FIND EQUVALIANT ARE NOT?

Comments

Since F is covering G and G is covering F, So they are equivalent...

---

BUT G IS ONLY ON FD

---

They are Equivalent...

---

Here AB->C is redundant right? because of A->C

Answer 1

F=AB->C,A->C    G=A->C

FOR EQUIVALENT(F MUST COVER G & G MUST COVER F)

F COVERING G :               A->C IS COVERED(IT SIMPLE IT IS IN BOTH FDS)

G COVERING F:               A->C IS COVERED

                                            AB->C IS COVERED ((AB)+=C IN G)
