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) =

g(x) = -5x + 1
a. bayangan dua pada g
g(2) = -5(2) + 1 = -10+1 = -9
2 → -9

b. g(0) = -5(0) + 1 = 0+1 = 1

c. g(x) = -5x+1
g(-1) = -5(-1) + 1 = 5 + 1 = 6
g(x)=6 , g(-1)=6 → g = 6/(-1) → g = -6

d. g(x) = -14
-5(x) + 1 = -14
-5x = -14 - 1
-5x = -15
x = -15/-5
x = 3

e. g(a) = 21
-5(a)+1=21
-5a = 21-1
-5a = 20
a = 20/-5
a = -4
