What is the domain for the piece of the function represented by f (x) = x+1

(-∞, ∞)

Step-by-step explanation:

As you can see for each value of x, f (x) is defined

example, for x = - 8000, f (x) is defined to be - 7999.

for x = 0, f (x) is defined to be 1.

for x = 8000, f (x) is defined to be 8001.

Also,

By its graph, Which is a straight line, So, it is defined everywhere

Thus,

its domain is (-∞, ∞)
