Help me please! I have to write the equation of the parabola in vertex form.
\n" ); document.write( "(show all work)
\n" ); document.write( "The vertex is (0,4) and it passes through point (1,2) \r
\n" ); document.write( "\n" ); document.write( "**
\n" ); document.write( "Standard form of equation for parabola: y=A(x-h)^2+k, with (h,k) being the (x,y) coordinates of the vertex, A being a multiplier which affects the steepness or slope of the curve.
\n" ); document.write( "For given problem:
\n" ); document.write( "y=A(x-0)^2+4
\n" ); document.write( "y=Ax^2+4
\n" ); document.write( "Using given point (1,2) to find A
\n" ); document.write( "2=A(1)^2+4
\n" ); document.write( "A=-2
\n" ); document.write( "Equation:
\n" ); document.write( "y=-2x^2+4
