Question

Jada saw a music video that her favorite artist recently posted online. The equation v(t)=320⋅4t represents the number of views v of the video, t days since Jada saw the video.

Part A: Find v(−2).

Answer 1

v(-2) = 20

Explanation:

The number of viewers, in t days after Jada saw the video, is given by:

`v(t) = 320*(4)^(t)`

Find v(−2).

This is v when
`t = -2`. So

`v(-2) = 320*(4)^(-2) = (320)/(4^2) = (320)/(16) = 20`

So

v(-2) = 20
