Which equation is represented by the graph below?

Step-by-step explanation:

From the given graph it is clear that,

1. Graph increasing exponentially.

2. It intersect the y-axis at y=-3.

3. As x approaches to a large negative number, then the function approaches towards -4.

So, the given graph represents an exponential function which shifts 4 units down.

The general form an exponential function is

When this function shifts 4 units down, then the equation of new curve is  

Therefore, the required equation is .

the answer is y = 11.54

hope this : )
