Sorcice 1: \( f_{m} \) la famille de fonctions définies par: \( f_{m}(x)=x^{2}-2 m x+8 m-16 \quad(m \in \mathbb{R}) \) 1) Montrer que 4 est une racine de \( f_{m} \) quelle que soit la valeur de \( m \).

A used book store buys a hardback book for \( \$ 1.50 \) and then sells it for \( \$ 5 \). Over time, the store sells the same number of books it buys. The store manager can use the equation \( P(x)=5 x-1.5 x \) to determine the store's profit, \( P(x) \), where \( x \) is the number of books that the store sells. Which statement about the book store is true based on the profit equation?
