Find the equation of the parabola with vertex (-2,0) and y intercept 4\r

\n" ); document.write( "\n" ); document.write( "y = a(x-h)² + k\r
\n" ); document.write( "\n" ); document.write( "Substitute (h,k) = (-2,0) and (x,y) = (0,4)\r
\n" ); document.write( "\n" ); document.write( "4 = a(0-(-2))² + 0\r

\n" ); document.write( "\n" ); document.write( "1 = a\r
\n" ); document.write( "\n" ); document.write( "Substitute for just a, h and k, not x or y\r
\n" ); document.write( "\n" ); document.write( "y = a(x-h)² + k\r
