How does the graph of f(x) = |x| compare with the graph of g(x) = -3|x|? Choose all that apply.

• The graph of g is a vertical stretch of the graph of f

• The graph of g is a vertical compression of the graph of f

• The graph of g is a reflection over the x-axis of the graph of f

• The graph of g is translated up 3 units on the y-axis

Answer explanation

The minus sign flips it and the 3 stretches it flatter.
