    Answer:

    -x² + 2x + 8

    Step-by-step explanation:

    Essentially we need to subtract g(x) from f(x):

    (f – g)(x) = f(x) – g(x) = (2x + 1) – (x² – 7)

    Distribute the negative:

    (2x + 1) – x² – (-7) = (2x + 1) – x² + 7

    Combine like terms:

    2x + 1 – x² + 7

    -x² + 2x + 8

    Thus, the answer is -x² + 2x + 8.
