Question

Diketahui suatu fungsi f(x)=2x+1 dan (f bundaran g)(x+1)= -2x^2-4x-1.nilai g(-2) adalah

Answer 1

2g(x + 1) + 1 = - 2x² - 4x - 1
2g(x + 1) = - 2x² - 4x - 2
g(x + 1) = - x² - 2x - 1
utk x = - 3
g(-3 + 1) = - (-3)² - 2(-3) - 1
g(-2) = - 9 + 6 - 1
= - 4

Answer 2

Apa ya???
maaf lupa mau jawab apa????
