Answer:
 Reflect across the y-axis.
 Stretch by a factor of 3. 
 Shift 2 units up.
Step-by-step explanation:
 Below are some transformations for a function   :
 :
 1. If  , the function is shifted "k" units up.
, the function is shifted "k" units up.
 2. If  , the function is shifted "k" units down.
, the function is shifted "k" units down.
 3. If  , the function is shifted "k" units right.
, the function is shifted "k" units right.
 4. If  , the function is shifted "k" units left.
, the function is shifted "k" units left.
 5. If  , the function is reflected over the x-axis.
, the function is reflected over the x-axis.
 6. If  , the function is reflected over the y-axis.
, the function is reflected over the y-axis.
 7. If  and
 and  , the function is  stretched vertically by a factor of "b".
, the function is  stretched vertically by a factor of "b".
 8. If  and
 and  the function is compressed vertically by a factor of "b".
 the function is compressed vertically by a factor of "b".
 Then, given the parent function   :
 :
  
 And knowing that the other function is:
  
 You can identify that the function  is obtained by:
 is obtained by:
 -  Reflecting the function   across the y-axis.
 across the y-axis.
 -  Stretching the function  vertically by a factor of 3.
  vertically by a factor of 3. 
 - Shifting the function  2 units up.
 2 units up.
