tentukan nila a dari fungsi g(x)=7x+8 jika dikettahui g(a)=-27

Bab Fungsi

g(x) = 7x + 8

g(a) = -27

g(a) = 7 ( a ) + 8
-27 = 7a + 8
-27 - 8 = 7a
- 35 = 7 a
- 35 / 7 = a
- 5 = a

dik ;
(=) g(x) = 7x + 8
(=) g(a) = -27
(=) g(x) = g(a) = 7a + 8 = -27
                                7a = -27 + (-8)
                                  a = -35/7
                                  a = -5

semoga bisa membantu ,,maaf kalau salah
