To find the domain of a function, it is most appropriate to create a graph. Domain satisfies the bounds for the x-axis, or the horizontal movement of the graph. \r
\n" ); document.write( "\n" ); document.write( "M(x)=5/x^2 - 9 is a rational function with the following graph: $\"+graph%28+300%2C+200%2C+-20%2C+20%2C+-20%2C+20%2C+5%2Fx%5E2+-+9%29+\"$ , so the domain is (-∞,∞).\r
\n" ); document.write( "\n" ); document.write( "L(x)=5x-4 is a linear equation with the graph: $\"+graph%28+300%2C+200%2C+-20%2C+20%2C+-20%2C+20%2C+5x-4%29+\"$ . As seen in the graph, it is a line that has no bounds in the Cartesian Coordinate plane.
\n" ); document.write( "Its domain is (-∞,∞).\r
\n" ); document.write( "\n" ); document.write( "G(x)=7x=4/x=4. If you can clarify the equation I can help you, but this is clearly not a function since there are three equal signs. \n" ); document.write( "
