Which function is represented by the graph below?

a. f(x) = 3x

b. f(x) = 3x − 3

c. f(x) = 3x + 3

d. f(x) = 3^(x + 3)

(this is exactly how the question is asked and i need )

The correct answer option is f(x) = 3^(x+3).

Step-by-step explanation:

We are to determine whether which of the given answer options represent the given graph.

A graph which has a similar shape like that of the given graph here (big on the left and crawling along the x-axis on the right) represents the exponential growth or decay.

Therefore, the only correct option we have here is f(x) = 3^(x+3).
