Diket : f (x) = 2x + 3, g (x) = 3 (x - 4) = 3x - 12Dit : (f - 2g) (x) ?
Penyelesaian :
g (x) = 3 (x - 4)
g (x) = 3x - 12
2 g (x) = 2 (3x - 12)
2 g (x) = 6x - 24
==> (f - 2g) (x)
= f (x) - 2 g (x)
= 2x + 3 - (6x - 24)
= 2x + 3 - 6x + 24
= -4x + 27
Jadi, jawaban yang tepat adalah A. -4x + 27
g(x) = 3(x - 4)
(f - 2g)(x)
= f(x) - 2g(x)
= 2x + 3 - 2(3(x - 4)
= 2x + 3 - 6x + 24
= -4x + 27
