Question

The function
f(x)=2x/(x^2+1)
is
1.)Even
2.)Odd
3.)Neither even nor odd
4.)The concept of being even or odd does 5.)not apply since this expression does not represent a function
6.)It is both even and odd.

Answer 1

If the Function is Even then f(-x) = f(x)

if the function is odd then f(-x) = -f(x)

hope this helps

Answer 2

so its not even or odd

Answer 3

choice 3

Answer 4

Did u Check ..?

Answer 5

how do i check

Answer 6

By putting x = -x and Check...i think..it is odd...

Answer 7

huh im still a little lost

Answer 8

It is an odd function...
f(-x) = -x/x^2 + 1 = -f(x)

Answer 9

is that how you would solve the problem

Answer 10

This is the actual way we solve this kind of problems, by replacing x with (-x)
and checking whether f(x) is equal to f(x) or -f(x)...

Answer 11

If f(x) = -f(x) . an odd function
if f(x) = +f(x) an even function
Hope this makes sense....

Answer 12

thanks

Answer 13

medal please...
