Pertanyaan

Di ketahui fungsi h: × ---> 4× + 2 pada himpunan bilangan bulat.Tentukan.
A.)nilai h(×) jika × = -3,
B.)h(0),
C.)nilai × jika h(×) = -14,
D.)nilai a jika h(a) = -16,

Itu di atas yg tanda "--->" itu tanda panah ya

Tolong di jawab...pliss

  • h (x) = 4x + 2

    a ) h(-3) = 4.(-3) + 2
    <====> = -12 + 2
    <====> = -10

    b ) h(0) = 4.0 + 2
    <====> = 0 + 2
    <====> = 2

    c ) h (x) = 4x + 2 = -14
    <=====> 4x = -14 - 2
    <=====> 4x = -16
    <=====> x = -16/4
    <=====> x = -4

    d ) h (a) = 4a + 2 = -16
    <=====> 4a = -16 - 2
    <=====> 4a = -18
    <=====> a = -18/4
    <=====> a = -4,5

    — Maaf bila ada kesalahan —
  • A) h(-3)= 4(-3) + 2 = -12 + 2 = -10
    B) h(0) = 4(0) + 2 = 2
    C) h(x) => 4x + 2 = - 14
    h(x) => 4x = -14 - 2 = -16
    h(x) => x = -16/4 = -4
    D) h(a) = 4a + 2 = -16
    h(a) => 4a = -16 -2
    h(a) => a = -18/4 = -4,5
