Just do the arithmetic: what is f(1)? What is f(0)?
Or, perhaps, what is your understanding of the domain of a function?
Hey everyone, My friend and I are being asked to find the domain for the following function and it's derivatives:
From what I can tell, it's R any real number, but my friend insists it's R any real number AND X doesn't equal -1. Who's correct?
f(1) is 0/1 which is zero. f(0) is -1/0 which is undefined... Guess that answers my question. It's R any real number expect x=0. We thought the f'(x) and f"(x) had something to do with the domain, but I guess we were wrong.
For the first function it is defined for all x if x does not equal 0.
