Let f '(x) > 0 and f "(x) > 0 for all x 1 < x 2 , then
A
f 
> 
>
B
f

C
f

D
None of these
Text Solution
Verified by ExpertsThe correct answer is:
B
(a,b,c )
f '(x) > 0 it means curve is increasing
f "(x) >0 it means curve is concave up.
f 
> 
y coordinate
on the curve > y coordinate of points divides the at point line segment joining (x 1 , f(x 1 ) 
and (x 2 , f(x 2 ))
same we can proof option (B,C,D).
