    f (x) - g (x) = - 3x-5 - (4x-2)

    distribute

    -3x-5 - 4x+2

    combine like terms

    -7x-3

    Answer:

    -7x-3

    Answer is (f - g) (x) = - 7x - 3

    Step-by-step explanation:

    We have:

    f (x) = - 3x - 5

    g (x) = 4x - 2

    We need to find: (f - g) (x)

    So, we can write:

    (f - g) (x) = f (x) - g (x)

    = (-3x - 5) - (4x - 2)

    = - 3x - 5 - 4x + 2

    = - 3x - 4x - 5 + 2

    (f - g) (x) = - 7x - 3

    So we get (f - g) (x) = - 7x - 3
