Answer:

Step-by-step explanation:

To find the sum of the functions f(x) and g(x), we simply need to add their individual expressions together. Here's a step-by-step explanation:

1. First, let's write down the expressions for both functions:

f(x) = x + 3

g(x) = x² - 4x

2. Now, we add the two expressions together, keeping in mind that we should add the terms with the same variable (x) and keep the constants separate:

f(x) + g(x) = (x + 3) + (x² - 4x)

3. Combine the x terms:

f(x) + g(x) = x + 3 + x² - 4x

4. Simplify the expression by canceling out the x terms:

f(x) + g(x) = x + 3 - 4x + x²

5. Rearrange the terms to have the exponents in ascending order:

f(x) + g(x) = x² - 3x + 3

So, the sum of the functions f(x) and g(x) is:

f(x) + g(x) = x² - 3x + 3
