determine which of the following exponential formula(s) represents i, v, vi in the graph above.

For this case what you should see is the behavior of each function to find the correct answer.
 We have functions of the type:
 f (t) = a * (b) ^ t
 Thus,
 For I, we have:
 f (t) = 30 * (1.05) ^ t
 For V we have:
 f (t) = 30 * (0.95) ^ t
 For VI we have:
 f (t) = 30 * (0.85) ^ t
 
 option c.

Option: c is the correct answer.

        c.  φ, ε and δ

Step-by-step explanation:

From the graph given to us we see that the graph passes through the same initial point that is the starting point is same i.e. when t=0.

Also, they attain the maximum value at t=0.

α:

Now when t=0 we have:

 Value=10

β :  

Now when t=0 we have:

 Value=10

χ:  

Now when t=0 we have:

 Value=10

δ:

Now when t=0 we have:

Value=30

ε:

Now when t=0 we have:

Value=30

φ:

Now when t=0 we have:

              Value=30

Hence, we see that δ , ε and φ are the three functions such that they have the same initial value.

Well what if i told you it wouldn’t matter, because in the future the pony dies, depending on what choice you make
