The function \( f(x) \) represents the cost of shipping a box that weighs \( x \) pounds. When we say that \( f(7) < 10 \), it means that the cost of shipping a box that weighs 7 pounds is less than $10.
In practical terms, this tells us that if Edwin ships a clay sculpture that weighs 7 pounds, he will incur a shipping cost of less than $10 for that specific shipment.
