Algebra.Com's Answer #600480 by anand429(138)![]() ![]() You can put this solution on YOUR website! Equate the function to 0 and solve for x \n" ); document.write( "At all those points, function intercepts x-axis \n" ); document.write( "y= -4x^2 - 4x - 6 = 0 \n" ); document.write( "=> 4x^2 + 4x + 6 = 0 \n" ); document.write( "=> 2x^2 + 2x + 3 = 0 \n" ); document.write( "=> This equation has no real solution since discriminant<0 \n" ); document.write( "Hence no x-intercept \n" ); document.write( " |
