What is the formula for average rate of change of f(x) over interval [a, b]?
(f(b) - f(a)) / (b - a)
What is a secant line?
A straight line that intersects a curve at two or more points
What does the average rate of change represent geometrically?
The slope of the secant line connecting two points on a curve
What happens to a secant line as the two points get closer together?
It approaches a tangent line that represents instantaneous rate of change
In physics, what does average rate of change of position s(t) represent?

5
What calculus concept is the limit of average rate of change as interval shrinks?
The derivative (instantaneous rate of change)
How does average rate of change relate to the slope formula from Algebra I?
They are the same formula; average rate of change is slope between two points
