Looking for a clear and student-friendly way to introduce reciprocal functions? This guided learning pack and practice worksheet builds from reciprocals to reciprocal functions of the form f(x)=k/x, focusing on domain and range, asymptotes, and sketching graphs (including the effect of k). Students then apply reciprocal models to real-life inverse proportion word problems Topics Covered ✅ Reciprocals of numbers and algebraic expressions ✅ The reciprocal function f(x)=k/x and the role of k ✅
