Algebra.Com's Answer #338119 by Flannery(124)![]() ![]() You can put this solution on YOUR website! Hi Stephanie, I see you are learning about functions. \n" ); document.write( "Usually the input value is the x value and the output value is the y value. \n" ); document.write( "The phrase you used in the question translates to y=1/2x-6. \n" ); document.write( "That may be written f(x)=1/2x-6 (pronounced function of x is one half of x minus six). It may be expressed as f(x) ONLY if for every input x there is ONLY one output y. Let's make a short table for y=1/2x-6. \n" ); document.write( "when y=0 \n" ); document.write( "0=1/2x-6; x=12 \n" ); document.write( "when y=1 \n" ); document.write( "1=1/2x-6; x=14 \n" ); document.write( "when y=2 \n" ); document.write( "2=1/2x-6; x=16 \n" ); document.write( "when x=1 \n" ); document.write( "y=1/2(1)-6; y=-5 1/2 \n" ); document.write( "when x=2 \n" ); document.write( "y=1/2(2)-6; y=-5 \n" ); document.write( "when x=3 \n" ); document.write( "y=1/2(3)-6; y=-4 1/2 \n" ); document.write( "Those are six sets of values for your equation. They describe a function. If you graphed this set of points on x,y coordinates they would make a straight line with a slope of 1/2 and an x intercept of (0,12) yintercept of (0,-6). I hope that got you started. \n" ); document.write( " |
