diketahui g(×) = mx + n. jika g(2) = 1 dan g(3) = -1, nilai m dan n berturut-turut...

- Fungsi -

Jika g(x) = mx + n

g(2) = 2m + n
1 = 2m + n
n = 1 - 2m

g(3) = 3m + n
-1 = 3m + n
-1 = 3m + (1 - 2m)
-1 = m + 1
-2 = m

maka,
n = 1 - 2m
n = 1- 2(-2)
n = 1+4 = 5

Jadi, nilai m = -2 dan n = 2

semoga membantu

g(x) = mx + n

g(2) = m(2) + n
1 = 2m + n

g(3) = m(3) + n
-1 = 3m + n

eliminasi:
2m + n = 1
3m + n = -1
________ -
-m = 2
m = -2

masukkan m = -2 ke salah satu persamaan
2m + n = 1
2(-2) + n = 1
-4 + n = 1
n = 5
