Fungsi g ditentukan oleh g(x) = -5x + 1 pada himpunan bilangan bulat. tentukan : a. bayangan 2 pada g b. nilai g(0) c. nilai g jika x=-1 d. nilai x jika g(x)=-14 e. nilai a jika g(a) = 21 tolongg yaa.. besok dikumpul.. terus pake cara yaa... pliss

Bagian a g(2) = -5(2) + 1 g(2) = -10 + 1 g(2) = - 9
bagian b g(0) = -5(0) + 1 g(0) = 1
bagian c g(-1) = -5(-1) + 1 g(-1) = 5 + 1 g(-1) = 6
bagian d g(x) -5x + 1 - 14 = -5x + 1 - 14 - 1 = -5x -15 = -5x x = (-15) : (-5) x = 3
bagian e g(a) = -5(a) + 1 21 = -5a + 1 21 - 1 = -5a 20 = -5a a = 20 : (-5) a = -4
g(2) = -5(2) + 1
g(2) = -10 + 1
g(2) = - 9
bagian b
g(0) = -5(0) + 1
g(0) = 1
bagian c
g(-1) = -5(-1) + 1
g(-1) = 5 + 1
g(-1) = 6
bagian d
g(x) -5x + 1
- 14 = -5x + 1
- 14 - 1 = -5x
-15 = -5x
x = (-15) : (-5)
x = 3
bagian e
g(a) = -5(a) + 1
21 = -5a + 1
21 - 1 = -5a
20 = -5a
a = 20 : (-5)
a = -4
