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.

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
