Enrich Define the average rate of change of y with respect to x for a function y = f(x) over the domain [a,b] as (Δy)/(Δx) = (change iny)/(change inx), that is (Δy)/(Δx) = (f(b) - f(a))/(b - a), and recognise (f(b) - f(a))/(b - a) as the gradient of the secant through (a,f(a)) and (b,f(b)) on the graph of y = f(x)

Extension and enrichment for students who are ready to go deeper: rich tasks, problem solving and open-ended challenges.
