The function f(x) is the wait time for an amusement park ride where x is the number of people in line. what is the practical domain for the function f(x)?

all integers
all whole numbers
all real numbers
all positive integers

The domain would be the set of all whole numbers.

Step-by-step explanation:

Integers are { -3, -2, -1, 0, 1, 2, 3}

Whole numbers are {0, 1, 2, 3, }

Real numbers are all numbers except imaginary number,

Positive integers are {1, 2, 3, 4, }

Given,

In the function f(x),

x represents the number of people in line,

We know that number of people can not be negative and it can be 0,

Thus, the possible value of x are 0, 1, 2, 3,

Also, the domain of a function is the set of all possible value of input,

Since,  x represent the input for the function f(x),

Thus, the domain of f(x) would be the set of all whole number.

Second option is correct.
