PLEASE HELLLPPP!!
The average salary for a real estate agent is $41,990 per year. A pilot makes on average $98,410. If you consider the earning potential of both over a 30 year period, what is the difference between the real estate agent's earnings as compared to the pilot's wages?

$56,420

$1,692,600

$1,161,290

$2,910,310

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.
