  1. f open parentheses x close parentheses equals 2 to the power of x end exponent    
  2. f open parentheses x close parentheses equals 2 x minus 3    
  3. f open parentheses x close parentheses equals 2 to the power of x end exponent plus 5    
  4. f open parentheses x close parentheses equals 2 to the power of x minus 1 end exponent    

Hint:

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.

The correct answer is: f open parentheses x close parentheses equals 2 to the power of x end exponent plus 5


    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.
    f open parentheses x close parentheses equals 2 to the power of x end exponent plus 5 is a vertical translation of the graph f left parenthesis x right parenthesis equals 2 to the power of x
