if f is a function satisfying f x+y if f is a field then f x is a pid if f is a continuous function if f is a real valued differentiable function if f is an odd function then f -x if f is a function then f 2+h f 2 +f h if f is a linear function then f r+s f r +f s if formula excel if function excel if formula with multiple conditions if functions if function excel multiple criteria

If f is a function such that f(b)-f(a)/b-a=2, then which of the following statements must be true?

Bladerunner1976: Based on the type of equation, f(b) relates to y2, f(a) relates to y1, b relates to x2, and a relates to x1. If we change those around we now get:
(y2 - y1)/(x2 - x1) which is the slope formula, or the average rate of change. thus your answer would be C
