Question

Can someone please check my answers and help me on a few unanswered questions?

1. Determine if the two functions are inverses of one another.
f(x) = -2x+1 g(x)=x-1/2

I said No

2. The function ƒ(x) = −x2 + 10 is not one-to-one. Find a portion of the domain where the function is one-to-one and find an inverse function.

I got The restricted domain for ƒ is [0,oo) and f^-1 (x) = sqrt(-x+10)

Answer 1

you are right
