Question

can i get help solving f(x)=10-x, find inverse f-1(x)_______

Answer 1

\[x=10-y\] solve for y you get
\[y=10-x\]
so
\[f^{-1}(x)=10-x\] it is it's own inverse

Answer 2

you can check. for example
\[f(3)=10-3=7\] and
\[f(7)=10-7=3\] so it is its own inverse

Answer 3

so what is the answer x+10?

Answer 4

can u show me the step by step process?
