Graph the transformed parabola using the table of values method (i.e. with the mapping rule)
Show calculation

  1. Translated 3 units left ⇒ y=(x+3)         
  2. Take reflection in x-axis ⇒ y= -(x+3)2    
  3. Vertical stretch by factor 2 ⇒ y= -2(x+3)2     
  4. Vertically translated up 1 unit ⇒ y= -2(x+3)2+1
