More Practice - Linear Transformations

Given the graph above, which equation shifts line down 5 units?

• y = 4x - 1

• y = 2x - 6

• y = 4x - 6

• y = 2x - 1

Describe the changes from the

graph of f to the graph of g.

• The graph of g is 4 units up the graph of f

• The graph of g is 4 units right of graph of f

• The graph of g is is 4 units left of graph of f

• The graph of g is down 4 units

  the graph of f

Describe the changes from the

graph of f to the graph of g.

• The graph of g is 2 units up of the graph of f

• The graph of g is 2 units left of the graph of f

• The graph of g went up

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

What change will happern if f(x) = x is replaced with f(x) + 2?

• Translation

  left 2 units

• Translation

  right 2 units

• Translation

  up 2 units.

• Reflection

  across the x-axis.

What change will happen if f(x) = x is replaced with 2f(x)?

• Line became steeper

• Line became less steep

• Lines became parallel

• Lines became perpendicular

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

• g(x) is shifted right 3 units

Which change will happen to y = x when it changed to y = -x?

• The line is a reflection across the y-axis

• The line will go down because the slope became negative.

• The line will be shorter.

• The line will go longer.

How did the equation, y = f(x + 7), shift from the linear parent function?

• Up 7 units

• Down 7 units

• Left 7 units

• Right 7 units

How did the equation, y = f(x + 7), shift from the linear parent function?

• Up 7 units

• Down 7 units

• Left 7 units

• Right 7 units

What is the equation of linear parent function?

• y = x

• y = mx + b

• f(x) = 2x

• y - y1 = m(x - x1)
