f(x) = -4x+2
g(x) = 6x^2 + 4x -5 
Find: g(x) + f(x) is it a function or not
g(x) + f(x)
(6x^2 + 4x - 5) + (-4x + 2)
6x^2 - 3 is your answer
~~
t(x) = 5x - 12x^2 and r(x) = -4x^2-5x+34
Find: r(x) + t(x) - is it a function
r(x) + t(x)
(-4x^2 - 5x + 34) + (5x - 12x^2)
-16x^2 + 34
~~
g(x)=(x^2-3x) 
f(x)=(6x-2) 
Find: g(x) *f(x) it is function
g(x) *f(x)
(x^2 - 3x)(6x - 2)
6x^3 - 20x^2 + 6x</PRE>
