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.

f

step-by-step explanation:

f

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
