Question on One One Many One and Into Onto

The function f:(-oo,-1)rarr(0,e^(5)) defined by f(x)=e^(x^(3)-3x+2) is (a)many one and onto (b)many one and into (c)one-one and onto (d)one-one and into

Following each of the following function find whether it is one-one or many-one and also into or onto f(x)=2tanx,(pi//2,3pi//2)toR

Number of One One and many one functions

One-one,many-one, into and onto function

The function f: R->R defined by f(x)=6^x+6^(|x|) is (a) one-one and onto (b) many one and onto (c) one-one and into (d) many one and into

f: N rarr N, where f(x)=x-(-1)^(x) .Then f is: (a)one-one and into (b)many-one and into (c)one-one and onto (d)many-one and onto

Classify the following functions in the form of one-one,many one,into and onto,also give reason to support your answer.

If f:N rarr N;f(x)=x-(-1)^(x) is (1) one one and into (2) Bijective (3) many one and into (4) many one and onto

Find whether the following function are one-one or many -one & into or onto if f:DtoR where D is its domain f(x)=|lnx|

Find whether the following function are one-one or many -one & into or onto if f:DtoR where D is its domain f(x)=1/(sinsqrt(|x|))
