maka nilai k adalah (beserta caranya)

-2(k) + 7 = 11
-2k + 7 = 11
-2k = 11 - 7
-2k = 4
k = 4 : (-2)
k = -2
Jawaban C

MAPEL = MATEMATIKA
KELAS = 8
BAB = RELASI & FUNGSI

diketahui =
rumus fungsi f(x) = -2x + 7
f(k) = 11

ditanya = nilai k??

f(x) = -2x + 7
f(k) = -2k + 7 = 11
f(k) = -2k = 11 - 7
f(k) = -2k = 4
f(k) = k = 4/-2
f(k) = k = -2

jadi nilai k = -2 ➡ C.

semoga membantu
