f(x) = : All real numbers greater than/equal to 5

Explanation: you can't square root negative numbers, and any number less than 5 would give us negative.

f(x) = : All real numbers except 8

Explanation: You can't divide by 0, and if we included 8 in the number set, we would get this: (this is impossible).

f(x) = : All positive real numbers and 0

Explanation: Again, you can't square root negative numbers.

f(x) = 8x : All real numbers

Not much to explain for this one, any real number makes this equation true.
