Algebra.Com's Answer #214547 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! write the equation of the parabola in standard form. find the coordinates of points corresponding to P and Q. \n" ); document.write( "*i do not really know how to explain this question but here is my work if it helps. my teacher marked it wrong and i do not know what i did wrong. \n" ); document.write( "f(x)= -3x^2 - 1x - 1 \n" ); document.write( "P' = (-2, 3) \n" ); document.write( "Q'= (-1, 0) \n" ); document.write( "*my teacher circled my answer for Q. i'm confused. \n" ); document.write( "================================== \n" ); document.write( "If you equation is correct. \n" ); document.write( "f(-2) = -3(-2)^2-(-2) -1 = -12 + 2 -1 = -11 \n" ); document.write( "giving you (-2,-11) as a point on the parabola. \n" ); document.write( "------------------------------------ \n" ); document.write( "Also, f(-1) = -3(1) -(-1) -1 = -3+1-1 = -3 \n" ); document.write( "giving you (-1,-3) \n" ); document.write( "---------------------------- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
