Pertanyaan

pada fungsi g(x) = 1/3 (x+4), jika g(a) = -2, maka nilai a = ...
A. -10
B. -6
C. -2
D. 2

Answer 1

Bab Fungsi
Matematika SMP Kelas VIII

g(x) = (1/3) . (x + 4)
g(a) = (1/3) . (a + 4) = -2
a + 4 = -2 . 3
a = -6 - 4
a = -10

Answer 2

g(a) = -2
⅓(a+4) = -2
⅓a + 4/3 = -2
⅓a = -2 - 4/3
⅓a = -6/3 - 4/3
⅓a = -10/3
a = -10/3 x 3
a = -10

Jawabannya A

Semoga membantu
