Question

The graph of f open parentheses x close parentheses equals 3 to the power of x end exponent minus 6 is translated from the parent function by _______.

  1. 6 units to the right    
  2. 3 units to the left    
  3. 3 units upwards    
  4. 6 units downwards    

hintHint:

The graph of f left parenthesis x right parenthesis equals 2 to the power of x end exponent plus k is a vertical translation of the graph of f left parenthesis x right parenthesis equals 2 to the power of x end exponent.
If k < 0, the graph is moved down.

The correct answer is: 6 units downwards


    The graph of f left parenthesis x right parenthesis equals 2 to the power of x end exponent plus k is a vertical translation of the graph of f left parenthesis x right parenthesis equals 2 to the power of x end exponent.
    If k > 0, the graph is moved up.
    If k < 0, the graph is moved down.
    Since the given function is f open parentheses x close parentheses equals 3 to the power of x end exponent minus 6 comma the parent function is translated vertically 6 units downwards.
