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

Option: c is the correct answer.

        c.  φ, ε and δ

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.
