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

B. g(0) = -5(0) + 1 = 1 c. g(-1) = -5(-1) + 1 = 6 d. g(-14) = -5(-14) + 1 = 71 e. g(a) = -5a + 1 21 = -5a + 1 21 - 1 = -5a 20 = -5a a = -4
= 1
c. g(-1) = -5(-1) + 1
= 6
d. g(-14) = -5(-14) + 1
= 71
e. g(a) = -5a + 1
21 = -5a + 1
21 - 1 = -5a
20 = -5a
a = -4
