Please go back to the source of this problem and double-check that you have copied the problem down correctly.  What operation happens between f and g in  (f  g)(x)?  Unclear.

I just did a problem like this.  You want to use substitution.

what do I SUBSTITUTE

mathmale · Answer

Again I ask you to look at your (f g)(x).   What is the relationship between f and g?

Is it a sum?:  a difference?   a product?  a quotient?  is g the input to f?  We cannot solve your math problem until you identify what operation is called for.

mathmale · Answer

If your original problem reads    'fg"   then you can assume it's multiplication.

But 'f g' is meaningless.
