(f-g) =
What is (f-g) = 9x ?
This is how you write "f of g of x" using *parentheses*
What is f(g(x)) ?

This is *another way* to write "f composed with g of x"
What is (f o g)(x) ?
f(x) = 3x and g(x) = 2x + 5
f(g(x))=
What is f(g(x)) = 6x + 15 ?
f(x) = 3x + 5 and g(x) = 2x + 6

(f+g)(x)=
What is (f+g) = 6x + 13 ?
The difference between f(g(x)) and g(f(x)).
What is f(g(x)) means you put g into f everywhere there is an x and g(f(x)) means you put f into g everywhere there is an x.
f(x) = 9x + 4 and g(x) = 5x + 2
(f o g)(x)= ?
What is (f o g)(x) = 45x + 22 ?
f(x) = 25x² and g(x) = 5x

What is (f+g)(x)=4x² + 15x - 7 ?
Explain how to find: (f+g)(x), (f-g)(x), (f*g)(x), and (f/g)(x)
What is... you take the two functions f(x) and g(x) and perform the indicated operations such as addition, subtraction, multiplication, or division.
