Algebra.Com's Answer #172795 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! What is the vertex of the graph of y = |2x - 3| - 5? What is the range of the function? \n" ); document.write( "You should be able to recognize that the value inside the absolute has to be positive or 0, \n" ); document.write( "therefore the the range (y) has to be - 5 or greater, right? \n" ); document.write( ": \n" ); document.write( "Plot a couple points here \n" ); document.write( "x = -3 \n" ); document.write( "y = |2(-3) - 3| - 5 \n" ); document.write( "y = |-6 - 3| - 5 \n" ); document.write( "y = |-9| - 5 \n" ); document.write( "Remove the absolutes \n" ); document.write( "y = 9 - 5 \n" ); document.write( "y = +4 \n" ); document.write( "Plot x/y point -3, +4 \n" ); document.write( ": \n" ); document.write( "Plot the value so that the value inside the absolute = 0 \n" ); document.write( "x = 1.5 \n" ); document.write( "y = |2(1.5) - 3| - 5 \n" ); document.write( "y = |3 - 3| - 5 \n" ); document.write( "y = 0 - 5 \n" ); document.write( "y = -5 \n" ); document.write( "Plot point x/y : 1.5, -5, the minimum range \n" ); document.write( "; \n" ); document.write( "x = +3 \n" ); document.write( "y = |2(3) - 3| - 5 \n" ); document.write( "y = |6-3| - 5 \n" ); document.write( "y = 3 -5 \n" ); document.write( "y = -2 \n" ); document.write( "Plot points x/y +3, -2 \n" ); document.write( ": \n" ); document.write( "Looks like this: \n" ); document.write( " |
