There is a straight line between the 2 points given. The domain is from 2 to 9 inclusive or[2,9], the range is [5,9] \n" ); document.write( "B. The domain is all real numbers. The range is from -infinity to infinity. \n" ); document.write( "C. y=|2x| The domain is all real numbers. The range is from 0 to infinity or [0,infinity) because 2x can't be negative. \n" ); document.write( "D. x=2+3y \n" ); document.write( "3y=x-2 \n" ); document.write( "y=(x-2)/3 \n" ); document.write( "Domain is all real numbers. Range is (-infinity,infinity). \n" ); document.write( ". \n" ); document.write( "Hope that helps. \n" ); document.write( ". \n" ); document.write( "Ed \n" ); document.write( " |
