Mrs. Tafolla graphs the function f (x) = x and

g (x) = f (x) -10 on the same coordinate grid. How are the graphs of f and g are related.

• The graph of f is shifted down 10 units to create the graph of g.

• The graph of f is steeper than the graph of g.

• The graph of f is less steep than the graph of g.

• The graph of f is shifted up 10 units to create the graph of g.
