Final answer:

To find (f-g)(x) for the functions f(x) = 2x² - 5x + 1 and g(x) = -2x + 4, we subtract g(x) from f(x) which results in the new function 2x² - 3x - 3.

Step-by-step explanation:

To operate (f-g)(x), we need to subtract the function g(x) from the function f(x). We are given f(x) = 2x² - 5x + 1 and g(x) = -2x + 4.

First, we write out the functions:


  • f(x) = 2x² - 5x + 1

  • g(x) = -2x + 4

Now we subtract g(x) from f(x):

(f-g)(x) = (2x² - 5x + 1) - (-2x + 4)

To subtract, we distribute the negative sign across g(x):

(f-g)(x) = 2x² - 5x + 1 + 2x - 4

Combine like terms:

(f-g)(x) = 2x² - 3x - 3

The result of the operation (f-g)(x) is 2x² - 3x - 3.
