find the x-intercepts of the parabola with vertex (1,1) and y-intercept(0,-3)
\n" ); document.write( "***
\n" ); document.write( "vertex form of equation for a parabola: y=A(x-h)^2+k, (h,k)=coordinates of vertex
\n" ); document.write( "solving for A:
\n" ); document.write( "-3=A(0-1)^2+1
\n" ); document.write( "A=-4
\n" ); document.write( "equation: y=-4(x-1)^2+1
\n" ); document.write( "x-intercepts
\n" ); document.write( "set y=0
\n" ); document.write( "-4(x-1)^2+1=0
\n" ); document.write( "(x-1)^2=1/4
\n" ); document.write( "x-1=±√(1/4)=±1/2
\n" ); document.write( "x=1±1/2
\n" ); document.write( "x-intercepts:
\n" ); document.write( "x=1/2
\n" ); document.write( "x=3/2
\n" ); document.write( "
