10 cards from this deck
How much output changes per unit change in input over an interval
A straight line passing through two points on a function's graph
f(b)−f(a)b−a\frac{f(b) - f(a)}{b - a}b−af(b)−f(a)
Change in function's output: f(b)−f(a)f(b) - f(a)f(b)−f(a)
Change in input: b−ab - ab−a
Change in
Gradient (slope) of the secant line
Rise over run
Average speed, rate of volume change, population growth rate
(a,f(a))(a, f(a))(a,f(a)) and (b,f(b))(b, f(b))(b,f(b))
