tolong bantu no 6 atau 7 🙏🏻

<p>6. Jika f (x) = x + 2 / 2x + 3 dan g(x) = 3x - 1 maka (g o f)(-2) adalah ...</p><p>&nbsp; &nbsp;<strong>Langkah 1:</strong> Temukan f (-2) dengan cara subsitusi ke f (x)</p><p>&nbsp; &nbsp;f (-2) = (- 2) + 2 / 2(- 2) + 3&nbsp;</p><p>&nbsp; &nbsp;f (-2) = (- 2) + 2 / (- 4) + 3</p><p>&nbsp; &nbsp;f (-2) = 0</p><p>&nbsp; &nbsp;<strong>Langkah 2:</strong> Temukan g (f (-2)) atau g (0) ke g (x)</p><p>&nbsp; &nbsp;g (0) = 3 (0) - 1</p><p>&nbsp; &nbsp;g (0) = - 1</p><p>&nbsp; &nbsp;<strong>Jadi, (g o f)(-2) = - 1</strong></p><p>7. Jika f(x) = x + 2 dan g(x) = 3x² + 4x + 1 maka &nbsp;(g o f)(x) adalah ...</p><p><strong>&nbsp; &nbsp;&nbsp;</strong>Temukan g (f (x)) dengan cara subsitusi f (x) kedalam g (x)</p><p>&nbsp; &nbsp; g (f (x)) = &nbsp;g (x + 2) = 3 (x + 2)² + 4 (x + 2) + 1</p><p>&nbsp; &nbsp; (x + 2)² = x² + 4x + 4</p><p>&nbsp; &nbsp; Sekarang substitusi ke dalam g (x + 2)</p><p>&nbsp; &nbsp; g (x + 2) = 3 (x² + 4x + 4) + 4 (x + 2) + 1</p><p>&nbsp; &nbsp; g (x + 2) = 3x² + 12x + 12 + 4x + 8 + 1</p><p>&nbsp; &nbsp; g (x + 2) = 3x² &nbsp;+ 16x + 21</p><p>&nbsp; &nbsp;&nbsp;<strong>Jadi, (g o f)(x) = 3x² &nbsp;+ 16x + 21</strong></p><p>&nbsp;</p><p><strong>Keseimpulan:</strong></p><p><strong>6.
