CPM Homework Help : GB8I Problem 9-87

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

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

Hint (a):

Look for a multiplier.

Answer (a):

$t(n) = 2 · 4^{n}$

Year ( $x$ )
$0$
$1$
$2$
$3$
$4$
$5$
$6$
Population $\left(f\left(x\right)\right)$
$5$
$6$
$7.2$
Hint (b):
What do you have to multiply $5$ by to get $6$ ?
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?

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