Question

Let f(p) be the average number of days a house stays on the market before being sold for price p in $1,000s. Which statement best describes the meaning of f(250)?

The house sold for $250,000.

The house stayed on the market for an average of 250 days before being sold.

This is the average number of days the house stayed on the market before being sold for $250,000.

The house sold on the market for $250,000 and stayed on the market for an average of 250 days before being sold.

Answer 1

we know that \(f(p)=\text{average days}\). We don't know a mathematical statement for the average number of days. The average number of days on the market is dependent on the price of the house \(p\).

Therefore \(f(250) =\) the number of days a house that sold for $250000 was on the market. So the first answer is correct.
