The number of hits on a website doubles every month. about 10,600 people visited the website during may. the expression 10,600 · 2t models the number of visitors after t months. evaluate the expression for t = 0 and t = −2. describe what each value of the expression represents in the situation.

If t = 0, this would indicate that no time has passed and therefore no visitors have since visited the website. (10,600 • 2(0)  = 0)

if t = -2, this would indicate that this is how many visitors there were in comparison to 2 months ago, which is why the number is negative to indicate that there were less visitors two months prior compared to now (10,600 • 2(-2) = -42,400)
