ax^2+bx+c
\n" ); document.write( "x^2-4x+3
\n" ); document.write( "(x-3)(x-1)=0
\n" ); document.write( "x=3, x=1 when y=0
\n" ); document.write( "The graph of the parabola has a minimum because a is positive.
\n" ); document.write( "(3+1)/2=2 so y will be at a minimum when x=2
\n" ); document.write( "f(x)=y=2^2-(4*2)+3
\n" ); document.write( "=4-8+3
\n" ); document.write( "=-1
\n" ); document.write( "The domain of x is all real numbers.
\n" ); document.write( "The range of y is -1 to infinity.
\n" ); document.write( "It is neither odd nor even with respect to the axis of the graph.
