Transformational Algebra

Choose the correct translated function.

• f(x)= |x|+2

• f(x)= |x|-2

• f(x)= -|x|

• f(x)= -|x|+2

Does the following shift up or shift down from the parent function y = |x|?
y = |x| - 8

• Shift up

• Shift down

Does the following get wider  or skinnier from the parent function y = |x|?
y = 5|x| 

• Wider

• Skinnier

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

• The graph of g is a vertical translation 2 units up of the graph of f

• The graph of f is a horizontal translation two units left of g

• The graph of g is a vertical stretch by a factor of 2 of the graph of f

• The graph of g is a reflection of the graph of f

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

• The graph of g is a vertical translation 4 units up from the graph f

• The graph of g is a horizontal translation of the graph of f, 4 units right

• The graph of g is a horizontal translation of the graph of f, 4 units left

• The graph of g is a vertical stretch of the graph of f, by a factor of 7

How does the graph of g(x) compare to f(x)?

• g(x) is steeper and shifted down from f(x)

• g(x) is steeper and shifted up from f(x)

• g(x) is flatter and shifted down from f(x)

• g(x) is flatter and shifted up from f(x)

• Function 2's graph is shifted down 8 units from Function 1's graph.

• Function 2's graph is shifted up 8 units from Function 1's graph.

• Function 2's graph is shifted left 8 units from Function 1's graph.

• Function 2's graph is shifted right 8 units from Function 1's graph.

• Function 2's graph is shifted down 6 units from Function 1's graph.

• Function 2's graph is shifted up 6 units from Function 1's graph.

• Function 2's graph is shifted left 6 units from Function 1's graph.

• Function 2's graph is shifted right 6 units from Function 1's graph.
