(f-g)(x)
(X²-4)-(x+2)
Jawab:
=0
Penjelasan dengan langkah-langkah:
A. (f+g)(x) = f(x)+g(x)
= (x+2)+(x²-4)
= x+2+x²-4
= x²+x+2-4
= x²+x-2
(f+g)(-1) = (-1)²+
(f-g)(x)
(X²-4)-(x+2)
Jawab:
=0
Penjelasan dengan langkah-langkah:
A. (f+g)(x) = f(x)+g(x)
= (x+2)+(x²-4)
= x+2+x²-4
= x²+x+2-4
= x²+x-2
(f+g)(-1) = (-1)²+
