Question

Find the value of k for the given exponential function.

  1. 3    
  2. 5    
  3. 4    
  4. 2    

Hint:

The exponential function is translated 2 units above.
So, the exponential function had vertical translation.

The correct answer is: 2


    The exponential function is translated 2 units above.
    So, the exponential function had vertical translation.
    If k > 0, the graph of an exponential function f open parentheses x close parentheses equals 2 to the power of x end exponent plus k moves up.
    Hence, the value of k is 2.
