combining functions: given f(x)=x-1, g(x)=√x, h(x)= x-1, find f∘g∘h

so i need to know how'd my answer was wrong and how'd the correct answer got to be the square root of -1-1.

45. f(x)=x-1, g(x)=[/FONT]√x, h(x)= x-1

f o g o h = f{g[h(x)]} = f{g(x-1)} continue...work from the inside out.

That cannot be correct. Please review your post and correct it.

That is not "the correct answer"! You mean sqrt(x- 1)- 1. Now, what answer did you give? We can't tell you why your answer is wrong without knowing what your answer was!
