Question 10 • Mathematics II
For a function of the form f(x) = a|x|, the graph is narrower than y = |x| when |a| is greater than 1, because its sides rise more steeply. In D, the coefficient is 4, so f(x) = 4|x| is narrower. The coefficient 0.5 in B makes the graph wider, while A and C only shift the graph.
