Why are there restrictions on the domain of a sequence when the sequence is defined as a function?

Step-by-step explanation:

If this sequence is a function, then for each input there can be exactly one output (function value), and these inputs must be integer.

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to
