Answer:

Translate the graph of y = 2(3)^x one unit to the left and four units down.

Step-by-step explanation:

It's essential to use parentheses around the exponent in this problem, to avoid ambiguity:  y = 2(3)^{x+1} - 4.

The original exponent was x.  This new exponent {x+1} represents a translation of the graph of y = 2(3)^x 1 unit to the left.

That -4 translates this resulting graph 4 units down.

Answer:

Option D

Step-by-step explanation:

In this question parent graph is y = 2(3)Ë£

and the translated graph is y = 2(3)ˣ⁺¹ -4

Translations done.

(1) Parent graph y = 2(3)ˣ is shifted one unit left on x-axis to form y' = 2(3)ˣ⁺¹

(2) Then y' is shifted 4 units down on y-axis giving the translated form y = 2(3)ˣ⁺¹ -4

Option D is the answer.
