`f:R->R` defined by `f(x)=3x+2` this function is one-one?

f:R rarr R defined by f(x)=3x+2 this function is one-one?

f:R^(+)rarr R^(+) defined by f(x)=1+2x^(2) this function is one-one?

A function f:R to R is defined by f(x)=2x^(2) . Is the function f one - one and onto ? Justify your answer.

Show that the function f: R rarr R defined by f(x) = (3x-1)/2, x in R is one-one and onto function.

Show that the function f: R to R defined by f(x)=2x^(2) , is neither one - one onto.

Show. that the function f: R rarr R defined by f(x)= (3x-1)/3, x inR is one-one and onto function.

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

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

Let a function f:R rarr R be defined by f(x) = 3 - 4x Prove that f is one-one and onto.

Show that the function f:R to R defined by f(x)=(x)/(x^(2)+1) is neither one-one nor onto.
