Is the equation given v(t) = 320 \cdot 4^{t}?


If yes, and you want to find the value of v(-3) then plug in t = -3, in the above equation to get


v(-3) = 320 \cdot 4^{-3} = 320 \cdot \frac{1}{4^{3}} = 5


You wanna know next what does v(-3) mean in this situation?  Aha!


It means the number of views, three days before Jada saw the video were 5.
