Fungsi f(x)=-6x+7 jika f(a)=-11 maka nilai x adlh

f(a) = -11 [ f(a) dimasukaan kedalam f(x)

f(x) = -6x + 7
f(x) = -6x + 7 = -11
f(x) = -6x = -11 - 7
f(x) = x = -18 / -6
f(x) = x = 3

Jadi , x = 3

Kalau boleh jadikan jawaban terbaik yah.

f(x) = -6x + 7
f(x) = -11

-11 = -6x + 7
6x = 7 + 11
6x = 18
x = 18/6
x = 3
