Hello!
In this problem, we are using function arithmetic.
The term f (x) is given, which is 3x² - 2x + 1.
The term f (2) is not given, but we know half of what the function is asking for. The function of f is 3x² - 2x + 1, but we are needed to find f (2). This means we substitute x = 2 into f (x). After that, combine like terms.
f (x) + f (2)
3x² - 2x + 1 + 3 (2) ² - 2 (2) + 1 (multiply)
3x² - 2x + 1 + 12 - 4 + 1 (simplify)
3x² - 2x + 10
Therefore, f (x) + f (2) is 3x² - 2x + 10.
