Question

Algebraically show that each of the given combinations are equivalent to the given functions. f(x) – g() is
equivalent to m(x) given:
f(0)
= – 3x + 5; g(x)
– 5x – 7; m(x) = 2x + 12
f(x) – g(x) = (
=

    Answer:

    f(x) - g(x) = 2x + 12

    m(x) = f(x) - g(x) — True

    Step-by-step explanation:

    Given

    f(x) = -3x + 5

    g(x) = -5x - 7

    m(x) = 2x + 12

    Solving (a): f(x) - g(x)

    From the given parameters, we have:

    f(x) = -3x + 5

    g(x) = -5x - 7

    So:

    f(x) - g(x)=-3x+5 + 5x + 7

    Collect like terms

    f(x) - g(x) = 2x + 12

    Solving (b) m(x) = f(x) = g(x)?

    In (a), we have:

    f(x) - g(x) = 2x + 12

    And

    m(x) = 2x + 12 — given

    By comparison:

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