solve 1 and 2 please

MHF 4U1 Part D: Communication 1. State the solution to f(x)=9(x), f(x)g(x) for the following graph. Write the solution for b) and c) in set notation. (3 marks) 8 y - f(x ) .alf x =g(x) 6- x -8(x ) 2- . b) f ( x) g(x) 2. Sandeep claims that (f . 9)(x) is the same as f(x) X 9(x). Is he right or wrong? What does (f . g)(x) actually mean
