Algebra.Com's Answer #8055 by rapaljer(4671)![]() ![]() You can put this solution on YOUR website! Start by graphing the function, and determine in what intervals of x the graph is above the x-axis. Notice that the roots (zeros) are at x= 0, x=1, and x=4, so the graph should cover these values of x and a little more on each side. Let's say graph from x=-2 to x= 6, and y from -20 to 20.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "After drawing the graph, notice that the graph is above the x-axis from \n" ); document.write( "(-inf, 0) union (1,4) union (4, inf).\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "R^2 at SCC \n" ); document.write( " |
