Algebra.Com's Answer #715088 by richwmiller(17219) You can put this solution on YOUR website! vertex at (2,-4) \n" ); document.write( "(x-h)^2=4p(y-k) \n" ); document.write( "(x-2)^2=4p(y+4) \n" ); document.write( "Without even calculating p the only option that matches is D.(x-2)^2=8(y+4) \n" ); document.write( "and yes p=2 \n" ); document.write( " \n" ); document.write( " |
