I first off here on this problem, We're gonna write this as a and function notation, so just replace the why with the FM back. So it's just f of X is equal to the square root of X minus one. So there's our function notation. And then for part B, we're gonna find f of five, which would be the square root of five minus one or the square to four by minus one is four and swear to four is to so f of five is too.
