Which value can fill in the blank in the function f(x) = |x| to make its graph wider than that of tge parent function f(x) =|x|

This piecewise function is equivalent to:

f(x) = a.|x|. 
The greater the coefficient "a" the narrower is the graph, and
the smaller the coefficient "a" the wider the graph
So if f(x) = |x|, then any coefficient smaller than 1 will widen the graph, like for instance: 

f(x) = 1/4|x|
f(x) = 0.8|x|
f(x) = 1/10|x|, etc.
