Algebra.Com's Answer #12067 by rapaljer(4671)![]() ![]() You can put this solution on YOUR website! If the number -5 is in the range, this means that f(x) = -5. The question is to find the element in the domain, that is, find the value of x that corresponds to y=-5.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "f(x) = 4x - 9 \n" ); document.write( "-5 = 4x -9\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Add +9 to each side: \n" ); document.write( "-5 + 9 = 4x -9 +9 \n" ); document.write( "4 = 4x\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Divide by 4: \n" ); document.write( "x= 1\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Ordered pair: (x,y) = (1, -5)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "R^2 at SCC \n" ); document.write( " |
