Q. Decompose the function f(g(x))=(x1)6 into f(x) and g(x).g(x)=f(x)=
Identify Composite Function: To decompose the function f(g(x))=(x1)6, we need to find two functions f(x) and g(x) such that when g(x) is plugged into f(x), we get the original composite function.
Choose g(x): Let's choose g(x) to be a function that will simplify to give us an expression that looks like (1/x)6 when plugged into another function f(x). A natural choice for g(x) is to take the reciprocal of x, so let's set g(x)=1/x.
Find f(x): Now we need to find a function f(x) such that when we plug g(x) into it, we get (1/x)6. Since g(x)=1/x, we want f(g(x))=f(1/x) to equal (1/x)6. Therefore, f(x) must take an input and raise it to the sixth power. So we can set f(x)=x6.
Verify Decomposition: To verify our decomposition, we can substitute g(x) into f(x) and check if we get the original function. Substituting g(x) into f(x), we get f(g(x))=f(x1)=(x1)6, which is indeed the original function.
Final Functions: Therefore, the functions f(x) and g(x) that decompose f(g(x))=(x1)6 are f(x)=x6 and g(x)=x1.
