Question 117458
The answer is false. The graph of {{{y = abs(x)}}} is shaped like the letter "V" as shown by this graph.
.
{{{graph (400,400,-20, 20, -5, 25, abs(x))}}}
.
On the left side of the y-axis the slope of the graph is -1 ... a negative slope because the graph is 
going down as you go to the right along the x-axis.
.
You need to convince yourself that the graph shown above is the graph of the absolute value
of x. Do this by selecting negative values and positive values of x and seeing if they give
you values of y that match the graph. 
.
Hope this helps you to understand the problem and how to view it so you can come up with the
answer to the question ... and to recognize that the answer is false.
