Question

diketahui fungsi f(x) = x² + 3 dan gof(x) = 3x² + 2, nilai g(x) adalah​

Answer 1

Verified answer

Jawaban:

g(x) = 3x - 7

Penjelasan dengan langkah-langkah:

f(x) = x² + 3

(gof)(x) = 3x² + 2

g(f(x) = 3x² + 2

g(x² + 3) = 3x² + 2

misal

a = x² + 3

x² = a - 3

g(a) = 3(a - 3) + 2

g(a) = 3a - 9 + 2

g(a) = 3a - 7

g(x) = 3x - 7
