How do we represent a translation 2 units to the left using function notation?

The graph of g(x) is a
(a)   translation ​ (b)   units ​ ​ (c)   the graph.

• vertical

• 2

• 1

• up

• down

• left

• right

Describe the transformation of y = g(x) for the function
y = 3g(x - 3) + 5

• Shifted up 5 units
  Shifted right 3 units
  Stretched vertically by a factor of 3

• Shifted up 5 units
  Shifted left 3 units
  Stretched vertically by a factor of 3

• Shifted down 5 units
  Shifted left 3 units
  Stretched vertically by a factor of 3

• Shifted down 5 units
  Shifted left 3 units
  Stretched vertically by a factor of 1/3

(Order matters) Select all possible combinations that correctly transforms:

y = g(x) to y = - 2g(x + 6) - 10
