Bab FungsiMatematika
Kelas 8 SMP
Penyelesaian
f (x) = ax + b
f (1) = 1a + b = 3 .... persamaan 1
f (2) = 2a + b = 5 .... persamaan 2
Eliminasi persamaan 1 dengan persamaan 2
1a + b = 3
2a + b = 5
-------------- -
-a = -2 (kedua ruas dikali -1)
a = 2
Subtitusikan ke persamaan 1
1a + b = 3
2 + b = 3
b = 1
Bentuk fungsi
f (x) = ax + b
f (x) = 2x + 1
