SUMMARY
The discussion focuses on the conditions under which the composition of two functions, defined as a=fx+g and b=hx+i, results in commutativity, specifically when a∘b equals b∘a. The derived expressions are a∘b(x)=fhx+gh+i and b∘a(x)=fhx+fi+g. To achieve equality, the coefficients and constants must satisfy the equations gh+i=fi+g, leading to specific relationships among the variables f, g, h, and i.
