The given vertex (origin) and point tell you that the vertex must be a largest x value. The value of \"a\" from standard form is some $\"a%3C0\"$ .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Filling in the form, $\"x=a%28y%29%5E2\"$ .
\n" ); document.write( " $\"a=x%2F%28y%5E2%29\"$
\n" ); document.write( "Use the point which is on the parabola;
\n" ); document.write( " $\"a=-2%2F%2825%29\"$ .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"highlight%28x=-%282%2F25%29y%5E2%29\"$ \n" ); document.write( "
