tolong di jawab kakk🙏 Diketahui (g ° f)(x) = 6x - 5 dan f(x) = 3x +1 Hasil dari g(x) adalah:

<p>Jawabannya adalah <strong>g(x) = 2x - 7.</strong></p><p><strong>Diketahui :</strong></p><ul><li>(g o f)(x) = 6x - 5</li><li>f(x) = 3x + 1</li></ul><p><strong>Ditanyakan : </strong>g(x) = ... ?</p><p><strong>Dijawab :</strong></p><p>&nbsp;(g o f)(x) = 6x - 5</p><p>&nbsp; &nbsp; &nbsp;g(f(x)) = 6x - 5</p><p>Mari kita gunakan f(x) sebagai permisalan, misalnya f(x) = y. Maka,</p><p>&nbsp; &nbsp;f(x) = y</p><p>&nbsp;3x+1 = y</p><p>&nbsp; &nbsp; &nbsp;3x = y - 1</p><p>&nbsp; &nbsp; &nbsp; &nbsp;x = (y - 1)/3</p><p>Nah, lalu kita masukan f(x) = y ke g(f(x)) = 6x - 5</p><p>&nbsp; g(f(x)) = 6x - 5</p><p>&nbsp; &nbsp; &nbsp; g(y) = 6x - 5</p><p>&nbsp; &nbsp; &nbsp; g(y) = (6(y - 1)/3) - 5</p><p>&nbsp; &nbsp; &nbsp; g(y) = (6y - 6)/3) - 5</p><p>&nbsp; &nbsp; &nbsp; g(y) = 2y - 2 - 5</p><p>&nbsp; &nbsp; &nbsp; g(y) = 2y - 7</p><p>Ubah menjadi y → x</p><p><strong>g(x) = 2x - 7</strong></p><p>&nbsp;</p><p>Ketemu :D🙏</p><p>Semangat mengerjakan&nbsp;</p>
