Algebra.Com's Answer #434049 by josgarithmetic(39617)![]() ![]() ![]() You can put this solution on YOUR website! Here is help with (a) and (b):\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "(a) \n" ); document.write( "Vertex will be at (h,k) for a parabola function in standard form, y=a(x-h)^2+k. Your given equation is in standard form so you can just read the values of h and k. \n" ); document.write( "Meaning: vertex is (3,8)\r \n" ); document.write( "\n" ); document.write( "(b) \n" ); document.write( "The parabola has a minimum if a is positive, and the parabola has a maximum if a is negative. In the given equation, a=-2. \n" ); document.write( "Meaning: vertex is a minimum \n" ); document.write( " |
