Mason is completing a study for his psychology course. For the study, he begins with $20 and asks individuals on the street if they want the money or if they would like him to double it and give it to the next person. He continues to do this until someone takes the money. This situation can be modeled by the exponential equation m(p)=20(2)p

To analyze the equation \( m(p) = 20(2)^p \):

  1. Understanding the function:

    • The variable \( p \) represents the number of people who choose to pass the money on.
    • The function calculates the amount of money \( m \) based on how many people have passed the money.
  2. Domain of the function:

    • \( p \) can be any non-negative integer because you can't have a negative number of people passing on the money. Thus, the domain is \( p \geq 0 \).
  3. Range of the function:

    • When \( p = 0 \), \( m(0) = 20 \).
    • As \( p \) increases, \( m(p) \) increases exponentially. There are no upper bounds, so \( m \) can take any value greater than or equal to 20. Thus, the range is \( m \geq 20 \).

Based on the analysis, the correct statement is:

The range (\( m \)-values) includes the values \( m \geq 20 \).
