To combine functions in Algebra II, just follow these simple steps:

1. Identify the Functions: First, know the functions you have. For example, you might have $f(x)$ and $g(x)$.

2. Choose the Operation: Next, decide what you want to do with these functions. Do you want to add, subtract, multiply, divide, or combine them in some way?

3. Perform the Operation:

   • If you’re adding, you would write it like this: [ (f + g)(x) = f(x) + g(x) ]
   • If you’re combining them, you would write: [ (f \circ g)(x) = f(g(x)) ]

4. Simplify: After you’ve done the math, try to make your answer as simple as possible.

5. Check Your Work: Finally, it helps to double-check what you did by using specific numbers.

That’s all there is to it! Happy problem-solving!
