Q :

if f(x) = x3 – x2 + 100x + 1001, then

(a) f(2000) > f(2001)

(b) f(1/1999) > f (1/2000)

(c) f(x+1) > f(x–1)

(d) f(3x – 5) > f(3x)

why....?? (reason)

friend you directly substitute the options in question for 3 and 4 and take any x value and verify and for 1 and d also substitute and approximate the value                                                                                                                                                                                          pls approve
