Graphs of Linear Transformations

The linear parent function, f(x) = x, is transformed to g(x) = f(x) + 3. Describe the transformation.

• g(x) is shifted up 3 units

• g(x) is shifted down 3 units

• g(x) is shifted left 3 units

Use the graphs of f and g to describe the transformation from the graph of f to the graph of g.

• Graph g is reflected and steeper by a factor of 3

• Graph g is steeper by a factor of 3

• Graph g reflected and less steep by a factor of 3

• Graph g reflected and steeper by a factor of 3

Use the graphs of f and g to describe the transformation from the graph of f to the graph of g.

• Graph g is less steep by a factor of 1/5

• Graph g shifted down 1 unit

• Graph g is steeper by a factor of 1/5

• Graph g shifted up 2 units

Use the graphs of f and g to describe the transformation from the graph of f to the graph of g.
