You can put this solution on YOUR website!
I agree with your answers for parts (a), (b), and (c).
\n" ); document.write( "
\n" ); document.write( "For (d), I say NO, because if it were symmetric with respect to the x-axis,
\n" ); document.write( "along with point (1,3) the graph should also contain its reflexion across the x-axis (1,-3),
\n" ); document.write( "y=4-x^2. expresses y as a function of x,
\n" ); document.write( "so for a given x value, such as x=1, there is only one value of y.
\n" ); document.write( "
\n" ); document.write( "For (e), I agree with the YES answer,
\n" ); document.write( "because the fact that x appears only squared, as \"x%5E2\"
\n" ); document.write( "meas that y will have the same value for x and -x,
\n" ); document.write( "so if the graph contains the point (x,y),
\n" ); document.write( "it must also contain the reflexion of (x,y) across the y-axis : the point (-x,y).
\n" ); document.write( "
\n" ); document.write( "For (f), I say NO, because if it were symmetric with respect to the x-axis,
\n" ); document.write( "along with point (1,3) the graph should also contain its reflexion across the origin: (-1,-3),
\n" ); document.write( "y=4-x^2. expresses y as a function of x,
\n" ); document.write( "so for a given x value, such as x=-1, there is only one value of y, y=3.
\n" ); document.write( "
\n" );
