all positive real

all real number greater
than or equal to 5
all real numbers
all real numbers
except 8

Step-by-step explanation:

1). f(z) =

   The given function 'f' is defined for (z - 5) ≥ 0

    z ≥ 5

   Therefore, domain of the function will be [5, ∞)

   Or "All real numbers greater than or equal to 5"

2).

    Domain: "All real numbers except 8."

    Since the given function is not defined for z = 8

3). f(z) =

    The given function is defined for every real numbers greater and equal to zero.

    Domain: "All positive real numbers and 0"

4). f(x) = 8x

    This function is defined for all real numbers.

    "Domain: All real numbers"
