The roles of domain and range are switched from function to inverse. \n" ); document.write( "Your given functional-form equation to start with is the upper half of a parabola with a horizontal symmetry axis. \n" ); document.write( "Try completing-the-square to have a better understanding of your given parabola.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Now, what you are starting with is \n" ); document.write( "The vertex for this given equation is (5/2,-49/4). \n" ); document.write( "The shape is horizontal parabola. \n" ); document.write( "DOMAIN: x values must be greater than 5/2. \n" ); document.write( "RANGE: y values are greater than or equal to -49/4.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "If you want to now use the simple method of just switching x and y roles in the given equation, you can; and just solve that for y; and remember you must choose the RIGHT-HAND branch of the function. \n" ); document.write( " |
