2 Jawaban

  • Materi : Fungsi

    f(x) = -3x - 2
    f(-3) = -3(-3) - 2
    f(-3) = 9 - 2
    f(-3) = 7

    f(5) = -3(5) - 2
    f(5) = -15 - 2
    f(5) = -17

    f(-3) + f(5)
    = 7 + (-17)
    = 7 - 17
    = -10
  • F(x) = -3x - 2

    Masuk pertanyaan :
    F(-3) + F(5) ?

    F(-3) = -3 (-3) -2
    F(-3) = 9 - 2
    F(-3) = 7

    F(5) = -3 (5) -2
    F(5) = -15 -2
    F(5) = -17

    F(-3) + F(5) = ?
    7 + -17
    -10.
