Algebra.Com's Answer #333727 by mananth(16946) You can put this solution on YOUR website! f(x)=-x^2+2x+8\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "y = -x^2+2x+8\r \n" ); document.write( "\n" ); document.write( "x=0, y =8 (0,8) \n" ); document.write( "when y = 0 \n" ); document.write( "x^2-2x-8=0 \n" ); document.write( "x^2-4x+2x-8=0 \n" ); document.write( "x(x-4)+2(x-4)=0 \n" ); document.write( "(x-4)(x+2)=0 \n" ); document.write( "x= 4 OR -2\r \n" ); document.write( "\n" ); document.write( "x Intercept points are (4,0) & (-2.0) \n" ); document.write( "so you know what the intercepts are \n" ); document.write( " |
