9-87.

For each table below, calculate the missing entries and write an equation.

1.  Month ($x$) Population $\left(f\left(x\right)\right)$ $0$ $1$ $2$ $3$ $4$ $5$ $6$ $2$ $8$ $32$

Look for a multiplier.

$t(n) = 2 · 4^{n}$

1.  Year ($x$) Population $\left(f\left(x\right)\right)$ $0$ $1$ $2$ $3$ $4$ $5$ $6$ $5$ $6$ $7.2$

What do you have to multiply $5$ by to get $6$?

2. Which function is growing at a faster rate, the one in part (a) or part (b)? How can you tell from the tables? How can you tell by looking at the equations?

Complete the tables in the eTool below to help you write the equations.
