Answer 1

Answer:

(f + g)(x) means f(x) + g(x)

General Formulas and Concepts:

Alg I

• Function Notation
• Combining like terms

Alg II

• Composite Functions

Step-by-step explanation:

(f + g)(x) is the number form of "f plus g of x", meaning that we add the functions f and g together respect to x.

Another way to write (f + g)(x) is f(x) + g(x), which is the number form of "f of x plus g of x", still meaning that we are adding the 2 functions together.
