The average rate of change of a function f on the interval [a, b] is best represented by the slope of:
a. The secant line that intersects f at (a, f(a)) and (b, f(b))
b. The tangent line that touches f at (a, f(a))
c. The tangent line that touches f at (b, f(b))
d. The secant line that intersects f at (f(a), f(b)) and (a, b)
Ans: a
