Question 958946
suppose the functions f and g are defined for all real numbers x as follows: f(x)=3x^2 
g(x)=2x
 write the expressions for 
(f+g)(x) = 3x^2 + 2x
-----------------------------------
(f-g)(x) = 3x^2-2x
---------------------------
(fxg)(-2) = f(-2)*g(-2) = 3(4) + 2(-2) = 12-4 = 8

------
