Fungsi f: R-R dan g:RR ditentukan oleh (x) = x²-4x+2 dan g(x) = 3x + 5. Nilai dari (gof) (-2) = ..​

Jawab:

Penjelasan dengan langkah-langkah:

g(x) = 3x + 5

f(x) = x² - 4x + 2

(gof)(x) = g(f(x))

= 3f(x) + 5

= 3 (x² - 4x + 2) + 5

= 3x² - 12x + 6 + 5

= 3x² - 12x + 11

(gof)(-2) = 3(-2)² - 12(-2) + 11

= 3(4) + 24 + 11

= 12 + 24 + 11

= 47
