Without graphing, find the line of symmetry. The answer is either A,B,C,or D. I
\n" ); document.write( "got Vertex: (-4,9)
\n" ); document.write( "f(x) = -(x + 4)2 + 9
\n" ); document.write( "---
\n" ); document.write( "Since the line of symmetry passes thru the vertex
\n" ); document.write( "the line of symmetry must be x = -4
\n" ); document.write( "---------------------------------------------
