how does f(2+2)=3 because that what my book says

can somebody explain this

Thanks!

You have a function f(x) = something, such that when you plug in f(4) you get out 3.

The function could be f(x) = x-1, but it could also be more complicated than that. Please provide us with the entire problem.

Thanks,
John

If the entire exercise, instructions and explanation included, is "f(2+2) = 3", then there is no way to "answer" this, because there is no question, nor even an intelligible statement. Sorry.

Please consult with your instructor regarding explanation. Thank you.
