Q. Decompose the function f(g(h(x)))=3(cosx+6) into f(x), g(x) and h(x).
Identify Functions: To decompose the function f(g(h(x)))=3cosx+6, we need to identify the innermost function, the middle function, and the outermost function.
Innermost Function: The innermost function is h(x), which is the argument of the cosine function. Since the cosine function is cos(x), we can deduce that h(x)=x.
Middle Function: The middle function is g(x), which is the argument of the exponential function. Since the exponential function is 3(cosx+6), and we have already identified that h(x)=x, we can deduce that g(x)=cos(h(x))+6=cos(x)+6.
Outermost Function: The outermost function is f(x), which is the exponential function. Since the base of the exponential function is 3 and the exponent is the result of g(x), we can deduce that f(x)=3x.
