R(z) = (f ∘g)(z) = f (g(z)) = √5z−8 R ( z) = ( f ∘ g) ( z) = f ( g ( z)) = 5 z − 8. and it turns out that it’s actually fairly simple to differentiate a function composition using the Chain Rule. We are thankful to be welcome on these lands in friendship. If f(x) and g(x) are two functions, the composite function f(g(x)) is calculated for a value of x by first evaluating g(x) and then evaluating the function f at this value of g(x), thus “chaining” the results together; for instance, if f(x) = sin x and g(x) = x 2, then f(g(x)) = sin x 2, while g(f(x)) = (sin x) 2. Therefore, the rule for differentiating a composite function is often called the chain rule. Moveover, in this case, if we calculate h(x),h(x)=f(g(x))=f(−2x+5)=6(−2x+5)+3=−12x+30+3=−12… You’re almost there, and you’re probably thinking, “Not a moment too soon.” Just one more rule is typically used in managerial economics — the chain rule.
