Let `f:R->R` and `g:R->R` be two one-one and onto functions such that they are mirror images of each other about the line `y=a`. If `h(x)=f(x)+g(x)`, then `h(x)` is (A) one-one onto (B) one-one into (D) many-one into (C) many-one onto

Let f: RrarrRa n dg: RrarrR be two one-one and onto function such that they are the mirror images of each other about the line y=a . If h(x)=f(x)+g(x),t h e nh(x) is (a)one-one and onto (b)only one-one and not onto (c)only onto but not one-one (d)neither one-one nor onto

Let f: R-> R , be defined as f(x) = e^(x^2)+ cos x , then is (a) one-one and onto (b) one-one and into (c) many-one and onto (d) many-one and into

All one-one function are onto functions

f(x) is a polynomial function, f: R rarr R, such that f(2x)=f'(x)f''(x). f(x) is (A) one-one and onto (B) one-one and into (C) many-one and onto (D) many-one and into

f: NrarrN, 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

All onto functions are one-one functions

If f:[0,oo]->[0,oo) and f(x)=x/(1+x), then f (a) one-one and onto (b)one-one but not onto (c)onto but not one-one (d)neither on-one nor onto

Show that the function f: R toR. defined as f (x) =x ^(2), is neither one-one nor 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
