Question

b. Indicate for each of the following potential functional dependencies, whether it is 
indeed a functional dependence or NOT.
1. NUMBER → TITLE
2. STARTPAGE → ENDPAGE
3. NUMBER → (STARTPAGE, ENDPAGE, PUBLICATIONS, VOLUME)
4. TECHNICAL_REPORT_ID → NUMBER
5. (PUBLICATION, VOLUME) → YEAR 
6. TITLE → NUMBER

Consider the following relation:
ARTICLES (NUMBER, TITLE, PUBLICATION, VOLUME, YEAR, STARTPAGE, ENDPAGE,
TECHNICAL_REPORT_ID)
The relation contains information on articles published in publications (Journals). Each article
has a unique number, title, and information on where to find it (name of the publication, what
volume, and on which pages is appearing), also the ID of the technical report is specified.
The following is an illustration of the relation:
