You can put this solution on YOUR website!
1. The domain of the function is the range of x such that the functions makes sense.
\n" ); document.write( "There are no limitations on x such that g(x) makes sense so the domain is
\n" ); document.write( "(\"-infinity\",\"infinity\")
\n" ); document.write( "2. Perpendicular lines have slopes that are negative reciprocals of each other. Your given line slope is -3. The line perpendicular to the given line would then have a slope of (-1/-3) or 1/3.
\n" ); document.write( "Use the point slope form of the line using the point (5,0).
