Fungsi komposisi (gof) (x) adalah..

<p><strong>f(x) = 2 - x</strong></p><p><strong>g(x) = x²+ 5x</strong></p><p><strong>(g o f) (x) = (2-x)² + 5 (2-x)</strong></p><p><strong>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= (4-4x+x²) + (10-5x)</strong></p><p><strong>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;= x² - 9x + 14</strong></p>
