y=3(x-3)(x-3). It asks to graph, find the x-intercept, and the axis of symmetry.
\n" ); document.write( "***
\n" ); document.write( "Remember this formula for a parabola: y=A(x-h)^2+k, (h,k)=(x,y)coordinates of the vertex.
\n" ); document.write( "y=3(x-3)(x-3)
\n" ); document.write( "y=3(x-3)^2+0
\n" ); document.write( "vertex:(3,0)
\n" ); document.write( "since A>0, parabola opens upward.
\n" ); document.write( "axis of symmetry: x=3
\n" ); document.write( "find the x-intercept:
\n" ); document.write( "set y=0
\n" ); document.write( "0=3(x-3)(x-3)
\n" ); document.write( "x-3=0
\n" ); document.write( "x=3
