Question

If f(x) =x+3/3 , then what is f–1(x) ?

1/3x + 1

3x – 3

3x + 3

3x + 1

Answer 1

Is f-1(x) the inverse function of f?

Answer 2

what?

Answer 3

I am just verifying if you're trying to determine the inverse of the given function.

Answer 4

yep that´s it

Answer 5

Thanks

This is quite simple. First I will replace f(x) by y.

Second, swap the roles of x and y.

Third, solve y in terms of x. That should be it :)

Answer 6

Let me write up the solution...
