Fungsi g(x) = mx – n. diketahui g(5) = –11 dan g(–3)= 13. tentukan=… a. nilai m dan n b. rumus dari fungsi g c. nilai g(3) dan g(6) TOLONG DIJAWAB YA!!! BESUK SUDAH HARUS DIKUMPULIN NICHH, TERIMA KASIH YG SUDAH MEMBANTU

G(x) = mx - n a) nilai m dan n -11 = 5m - n 13 = -3m - n _____________ (-) -24 = 8m -3 = m
a) nilai m dan n
-11 = 5m - n
13 = -3m - n
_____________ (-)
-24 = 8m
-3 = m
5m - n = -11
-15 - n = -11
-n = 4
n = -4
b) f(x) = -3x + 4
c) g(3) = -3(3) + 4 = -9 + 4 = -5
g(6) = -3(6) + 4 = -18 + 4 = -14
