Algebra.Com's Answer #95453 by cngriffith(27)![]() ![]() ![]() You can put this solution on YOUR website! The domain is the x value. The range is the y value. Alphabeticly domain comes before range. Alphabaticly, x comes before y. Therefore x=domain and y= range.\r \n" ); document.write( "\n" ); document.write( "x-2y=1 \n" ); document.write( "x=2y+1 Solve equation for x. \n" ); document.write( "x=2(-2) +1 \n" ); document.write( "x=-4+1=-3 Substitute the first value in the range for y and solve for x. \n" ); document.write( " Continue this process for each number in the range. \n" ); document.write( "x=2(0)+1 \n" ); document.write( "x=1\r \n" ); document.write( "\n" ); document.write( "x=2(5)+1 \n" ); document.write( "x=11\r \n" ); document.write( "\n" ); document.write( "x=2(8)=1 \n" ); document.write( "x=17 \n" ); document.write( "Domain is -3,1,11,17 \n" ); document.write( " |
