a tank is draining water such that the volume is given with an exponentially decreasing graph as shown in the graph below. If the volume was modeled with an equation of the form V = a(b)^t, where t is the number of hours, then which of the following is the best value for b?

Answer is in the photo. I couldn't attach it here, but uploaded it to a file hosting. link below! Good Luck!

b.-4 units

all you   do is count how many times you move

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
