Show `f:R rarr R` defined by `f(x)=x^(2)+4x+5` is into

f:R rarr R defined by f(x)=x^(2)+5

f:R rarr R defined by f(x)=x^(3)-4

Show f:R rarr R " defined by " f(x)=x^(2)+x " for all " x in R is many-one.

Consider a function f:R rarr R defined by f(x)=x^(3)+4x+5 , then

f:R rarr R defined by f(x)=(x)/(x^(2)+1),AA x in R is

Show that the function f:R rarr R defined by f(x)=x^4+5 is neither one one nor onto

Classify f:R rarr R, defined by f(x)=5x^(3)+4 as injection,surjection or bijection.

The function f:R rarr R defined by f(x)=x(x-2)(x-3) is

Show that the function f:R rarr R defined by f(x)=(x)/(x^(2)+1)AA x in R is neither one-one nor onto.Also if g:R rarr R is defined by g(x)=2x-1 find fog(x)

the function f:R rarr R defined as f(x)=x^(3) is
