Question

Jada saw a music video that her favorite artist recently posted online. The equation v(t) = 425 (5)^t represents the number of views, v of the video, t days since Jada saw the video.

Find v(-2). Show your work.

Answer 1

The result to v(-2) taking into account the given equation is:

• 17 views.

Explanation:

To obtain the result to v(-2), you must understand that v(-2) means the number of views that the video had two days before Jada saw the video. Then, using the equation:

• v(t) = 425 * (5)^t

And replacing it we have:

• v(-2) = 425 * (5)^(-2)
• v(-2) = 425 * 0.04
• v(-2) = 17

As you can see with the calculations, the number of views of the video two days before Jada saw it were 17.
