The task is incomplete. The second function is missing.

Explanation:

To find a composition of functions you need two functions: #f(x)# and #g(x)#. If you have the 2 functions to find a composition you follow such procedure:

  • To find #f(g(x))#: In formula of #f(x)# you replace every occurance of #x# with formula of #g(x)#
  • To find #g(f(x))#: In formula of #g(x)# you replace every occurance of #x# with formula of #f(x)#
