Hello Everybody. Now i am going to teach you about function notation.
First lets get the formulas:
(f + g)(x)= add equations
(f - g)(x)= subtract eqns
(f *g)(x)= multiply (closed circle)
(f/g)(x)= divide
(f o g)(x) or f(g(x))= replace all x's in the f(x) eqn w/ the eqn g(x)
Now lets do a few examples so you can get the hang of it. YAYYYYYYYY
ex 1: f(x)= x + 4 g(x)= x + 2. Find the rule for (f + g)(x)
you simply just add the equations
(x + 4) + (x + 2)= 2x+6
ex 2 " "
