Combine standard function types arithmetically to create models.
Form and interpret \((f-g)(x)\)
Problem
Subtract functions \(R(x)=x(50-x)\) and \(C(x)=100\) to model net value or difference.
Big Picture
What this problem is really about
A net-value difference preserves the stated order: revenue first, then the entire cost output. We’ll substitute both rules with full grouping, remove the constant grouping without moving it inside the revenue product, and expand only as an equivalent check on signs and order.
