Do you know the shape of the graph of y = |x|? If not then plot some points to example the shape.
y = |x|
Now plot the points
and sketch the graph
Graph of y = |x|
This is a useful graph to know.
Now you want to modify the function, for example to plot the graph of y = |x| + 5. The relationship between y = |x| and y = |x| + 5 is that in the second expression, for each value of x the y value is increased by 5. Thinking of the graph, the y-values are shifted upwards by 5 units. Thus the graph is
graph of y = |x| + 5
