Question

the table shows the number of people p(t), register for a conference t days after registration opens. which function best approximates the data?

Answer 1

The function which aproximates better the data is:

`P(t)=20(2^t)`

because:

`P(0)=20`
`P(1)=20(2)=40`
`P(2)=20(2^2)=80`
`P(3)=20(2^3)=20(8)=160`
`P(4)=20(2^4)=20(16)=320`
