Answer:
A. both a relation and a function
Step-by-step explanation:
The given set of ordered pairs is 
{(1,2),(2,3),(3,1),(4,4),(5,2)}.
This ordered pairs represent a relation. 
The x-coordinates represent the domain and the co-domain or range is the set of the y-coordinates.
The relation is many-to-one relation. 
All many-to-one relations are functions.
The correct choice is A.

Answer:
(x - 3) inches
Step-by-step explanation:
the ratio of -15 (of the area term) and +5 (of the length term) suggests a term for the width ending in -3. and we need an x in there to get x² for the area.
so, immediate assumption is (x-3) for the width. 
let's check
(x+5)(x-3) = x² + 5x - 3x - 15 = x² + 2x - 15
correct.
