Question

Can anybody solve this one... Find a formula for f inverse (y). That is, solve for x in terms of y.
y= x^6 + 2x^3 + 1.

Answer 1

i can give me a sec k?

Answer 2

let me know if you can open this

Answer 3

i left off my minus

Answer 4

suppose to be plus or minus

Answer 5

we should probably restrict its domain to make it one to one

Answer 6

\(s^6+2x^3+1\) is not one-to-one function, so it does not have an inverse function, except if you make a restriction in its domain.

Answer 7

\(x^6+2x^3+1\)*

Answer 8

if we do the domain of f as (0,infinity),
then f inverse equals (-1+sqrt{x})^(1/3)

Answer 9

Thank you very much you guys!
