8-25.

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

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

What is the multiplier?

 $x$ $y$ $0$ $1.2$ $1$ $3.96$ $2$ $13.068$ $3$ $\mathbf{43.1244}$ $4$ $\mathbf{ \approx 142.31}$

$y = 1.2(3.3)^x$

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

$y = 5(6)^x$
