G(-3) = -3a + b = -15 g(3) = 3a + b = 9 ----------------------------- - = -6a = -24 = a = 4 masukkan a ke salah satu persamaan 3.4 + b = 9 12 + b = 9 b = 9 -12 b = -3 A. g(x) = 4x - 3 B. g(10) = 4.10 - 3 40 - 3 = 37
g(3) = 3a + b = 9
----------------------------- -
= -6a = -24
= a = 4
masukkan a ke salah satu persamaan
3.4 + b = 9
12 + b = 9
b = 9 -12
b = -3
A. g(x) = 4x - 3
B. g(10) = 4.10 - 3
40 - 3
= 37
