You can put this solution on YOUR website!
Since this is absolute value function, we should be able to tell 3 things just by looking at the function:
\n" ); document.write( "(i) vertex
\n" ); document.write( "(ii) open up or down
\n" ); document.write( "(iii) wide, regular, skinny graph
\n" ); document.write( "---
\n" ); document.write( "(i) The vertex is at (4,5)
\n" ); document.write( "(ii) It opens down, because there is a (-) sign in front of the absolute value.
\n" ); document.write( "(iii) It is wide since there is a 1/2 in front of the absolute value.
\n" ); document.write( "--
\n" ); document.write( "to graph, plot (4,5). Then pick x = 2. We get
\n" ); document.write( "-1/2|2-4|+5 = 4. So, (2.4)
\n" ); document.write( "Now pick x = 6.
\n" ); document.write( "-1/2|6-4|+5 = 4. So, (6,4).
\n" ); document.write( "Make a rough sketch and you are done.
\n" ); document.write( "
\n" );
