Question

if R tends R defined by f(x)=x^4​

Answer 1

Step-by-step explanation:

f:R→R is defined as f(x)=x

4

Let x,y∈R such that f(x)=f(y)

⇒x

4

=y

4

⇒x=±y

f(x

1

)=f(x

2

)



=x

1

=x

2

f(−1)=f(1)=1

F is not me -me

Consider an element 2 in codomain R

Then it is clear A any x∈R

Such that f(x)=2

So f is not onto

So f is neither one-one nor onto.
