find the vertex, the line of symmetry,
\n" ); document.write( "the maximum or minimum value of the quadratic
\n" ); document.write( "function and graph the function
\n" ); document.write( "f(x)=7-x2 and find zeros
\n" ); document.write( "You have a quadratic with a = -1, b = 0, c = 7
\n" ); document.write( "-----------------
\n" ); document.write( "Max or min occurs when x = -b/2a = -0/-2 = 0
\n" ); document.write( "f(0) = 7
\n" ); document.write( "So the vertex is (0,7)
\n" ); document.write( "------------------------------
\n" ); document.write( "Axis of symmetry is x=0
\n" ); document.write( "-------------------------------
\n" ); document.write( "Zeroes: 7-x^2 = 0
\n" ); document.write( "x^2 = 7
\n" ); document.write( "x = +sqrt(7) ; x = -sqrt(7)
\n" ); document.write( "====================================
\n" ); document.write( "Graph:
