anonymous · Answer

Which function below is the inverse of f(x) = x2 − 16?

anonymous · Answer

Make f(x)=x and x=y, then solve for y

anonymous · Answer

but what is the answer?

anonymous · Answer

nspire is completely correct but don't forget that if it is x^2 when you solve for the inverse, you need to take the complete root, i.e. + or - square root to get a complete inverse

bradely · Answer

are u satisfied my answer

xapproachesinfinity · Answer

X^2-16 doesn't have an inverse. it does not pass th one to one property or horizontl line test

xapproachesinfinity · Answer

you should restrict the function to some domain first to be able to invert this one

xapproachesinfinity · Answer

post the complete problem. it seems there missing info

xapproachesinfinity · Answer

first thing to check is whether the function satisfies the one to one property or not then you start solving to find the inverse

anonymous · Answer

^^ it doesn't have an inverse function but you can describe the equations relating its inverse using two functions.

xapproachesinfinity · Answer

that is true, that's I asked him to post the complete problem so we know what we looking for
based on what he put the answer is no inverse!
