Show that increasing functions and decreasing functions are one-to-one. That is, show that for any x, and x2 in I, x2 # x, implies f(x2)# f(x1). What are the definitions of increasing and decreasing functions? O A. Afunction is increasing if f(x,) > f(x2) for some x, and x2, and a function is decreasing if f(x,) < f(x2) for some x, and x2. O B. A function is increasing if f(x,) < f(x2) whenever x, f(x2) whenever x, f(x2) for some x, and x2. O D. A function is increasing if f(x,) > f(x2) whenever x, > x2, and a function is decreasing if f(x,) < f(x2) whenever x,
