You can put this solution on YOUR website!
T do not know what you are already supposed to know, and/or how you are expected to solve the problem, but maybe some of what follows will sound familiar.
\n" ); document.write( "The equation $\"x%5E2-y%5E2=9\"$ represents and graphs as a hyperbola,
\n" ); document.write( "a set of two curves that look like an inverted set of brackets,
\n" ); document.write( "like a corset fastened around the origin, looking like this )+( .
\n" ); document.write( "For the points on those curves, $\"x%5E2-y%5E2=9\"$ .
\n" ); document.write( "The points in between those curves have smaller $\"x%5E2\"$ values that the points directly to their left and right on the hyperbola,
\n" ); document.write( "so for those points, $\"x%5E2-y%5E2%3C9\"$ .
\n" ); document.write( "The points on the outside of the hyperbola have larger $\"x%5E2\"$ values that the points at the same height (same $\"y\"$ ) on the hyperbola,
\n" ); document.write( "so for those points, $\"x%5E2-y%5E2%3E9\"$ .
\n" ); document.write( "I would graph the hyperbola as dashed lines and would color the space outside the two curves, like this:
\n" ); document.write( " $\"graph%28300%2C150%2C-10%2C10%2C-5%2C5%2Cx%5E2-y%5E2%3E9%29\"$
\n" ); document.write( "Maybe you are expected to make a table of (x,y) value pairs, plot the points and join them with two curves.
\n" ); document.write( "Maybe you know about hyperbolas, their asymptotes and vertices, and that will allow you to draw a better hyperbola. \n" ); document.write( "
