Question
If f(x) = 
, then-
, then-Options
A.f(x) is increasing in [-1 , 2]
B.f(x) is continuous in [-1 , 3]
C.f(x) is maximum at x = 2
D.all the above
Solution
f(x) = 
f′(x) =
f(x) is increasing in [-1, 2]
f(x) is continuous [-1, 3]
and max. at x = 2
all the above
f′(x) =
f(x) is increasing in [-1, 2]
f(x) is continuous [-1, 3]
and max. at x = 2
all the above
