Let
  1. Write a formula for the transformation and geometrically describe the transformation.
    To do this, use the blank method: write the output but replace all instances of the variable with the new input, Remember to use parentheses when substituting this in for
    Formula:
    For the geometric description, remember that we are taking the opposite of the input variable, so this will affect the graph’s position in the horizontal direction.
    Description: will reflect the graph of over the
  2. Write a formula for the transformation 7
    Notice that there are two changes here: Subtracting 7 from the input, and the opposite symbol outside.
    First apply the inside change by replacing all instances of the variable with the new input, Remember again to use parentheses when substituting this expression for
    This would leave us with:
    (8(9
    Next, apply the outside change by putting the opposite symbol outside of this whole expression, again remembering to use parentheses.
    Formula: 7
    The inside change of subtracting 7 will move the graph in the horizontal direction. The outside change of taking the opposite will affect the output values by changing their sign.
    Description: will shift the graph of by 7 units and reflect it over the
