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

1. Jawaban Shireii
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

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
