Matematika diket : f(x) = x²-1
g(x) = 2x+3
ditanya : nilai (f o g) (0) ?​

diket : f(x) = x²-1
g(x) = 2x+3
ditanya : nilai (f o g) (0) ?​

Jawaban:

8

Penjelasan dengan langkah-langkah:

(f o g)(x) = f(g(x))

= f(2x + 3)

= (2x + 3)² – 1

= 4x² + 12x + 9 – 1

= 4x² + 12x + 8

∴ (f o g)(0) = 4(0)² + 12(0) + 8

= 0 + 0 + 8

= 8 ✔️
