Question

Tolong, ya? Ini tentang fungsi komposisi.

Answer 1

1) (f×g)(x) = f(x) × g(x)
=(x^2-4) (3x-5/x-2)
=(x-2)(x+2) (3x-5/x-2)
=(x+2) (3x-5)
= 3x^2 -5x + 6x -10
= 3x^2 + x -10

2) f(x) × g(2/3)
= (5-3x) × (9(2/3) +1/(2/3)-1)
=(5-3x) × (6+1 / -1/3)
=(5-3x) × (-7/1/3)
=-35/1/3 + 21/1/3 x
=(-35 × 3/1) +( 21 × 3/1)x
=-105 + 63x
