Average Rate of Change (HSC SSCE Mathematics Advanced): Flashcards

How much output changes per unit change in input over an interval

A straight line passing through two points on a function's graph

$\frac{f(b) - f(a)}{b - a}$

Change in function's output: $f(b) - f(a)$

Change in input: $b - a$

Change in

Gradient (slope) of the secant line

Rise over run

Average speed, rate of volume change, population growth rate

$(a, f(a))$ and $(b, f(b))$
