To analyze the equation \( m(p) = 20(2)^p \), we can break down the statements provided:
-
Domain (p-values): The values for \( p \) represent the number of people who opt to pass on the money. Since individuals can either take the money or pass it on, \( p \) must be a non-negative integer (e.g., 0, 1, 2, ...). Therefore, the domain is \( p \geq 0 \), not \( p \geq 20 \).
-
Range (m-values): The value of \( m \) starts at \( 20(2)^0 = 20 \) when \( p = 0 \) and increases as \( p \) increases. As \( p \) approaches infinity, \( m \) will also approach infinity. Hence, the range is \( m \geq 20 \).
-
Behavior of m as p increases: Based on the equation, as \( p \) increases, \( m \) increases exponentially. Therefore, as \( p \) increases, \( m \) increases quickly at first and then continues to increase, but it never decreases.
Considering the analysis above, the true statement is:
- The range (m-values) includes the values (m ≥ 20).
