Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

B check attachment
this derivative is in correct, please check.
understand this
sir, you found the interval where the f(x) is increasing and decreasing but how is that connected to f(x) being one-one?
we select that interval in which f only increase or decrease
par sir usse one-one ko kya lena dena?
????
check three graph first increase second decrease third neither increase nor decrease
one one means no value repeat .if f increase or decrease then no f(x) repeat
