CPM Homework Help : CCA Problem 7-24

Each table below represents an exponential function of the form $y=ab^x$ . Copy and complete each table on your paper and find the corresponding equation.

x
y
$0$
$1.2$
$1$
$3.96$
$2$
$13.068$
$3$
$4$

Hint (a):

What is the multiplier?

Answer (a):

$x$	$y$
$0$	$1.2$
$1$	$3.96$
$2$	$13.068$
$3$	$\color{red}{43.1244}$
$4$	$\color{red}{\approx142.31}$

$y = 1.2\left(3.3\right)^{x}$

x
y
$0$
$5$
$1$
$2$
$180$
$3$
$4$

Hint (b):

$x$	$y$
$0$	$5$
$1$	$\color{blue}{30}$
$2$	$180$
$3$	$\color{blue}{1080}$
$4$	$\color{blue}{6480}$

Answer (b):

$y = 5\left(6\right)^{x}$
