Question

f^(-1)(x)=((x^2)/(2))-3

Find the Domain :)

Answer 1

\[\textbf{HINT}\]There is no such \(x\) that may make any fraction undefined.

Answer 2

Okay, so what if f(x) was actually the inverse.
f^(-1)(x)=((x^2)/(2))-3

Answer 3

Okay, so the function you're given is \(f'(x)\) and you have to find the domain in \(f(x)\). Right?

Answer 4

no, the inverse domain. so they gave me f(x). I found the inverse, then they asked for the domain of the inverse. I thought it was all real numbers, but when I typed it in, it told me I was wrong.

Answer 5

It \(\underline{\textbf{is}}\) all real numbers.

Answer 6

Are you sure you computed the inverse function right?

Answer 7

That's what I thought..... Well, it's probably a glitch for the website I have to use for my math class. This sucks. and I'm pretty sure.

Answer 8

Math classes suck. Totally.

Answer 9

ha, right, right.... Thanks though.

Answer 10
