Question

If f(x) is 3x^2 - 2x +1 what is f(x)+f(2)

Answer 1

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.
