8-112.

Each table below represents an exponential function in $f(x) = ab^x$ form. Copy and complete each table on your paper and then write an equation for the function.

1.  $x$ $f(x)$ $-1$ $3$ $0$ $1$ $75$ $2$ $3$

What is the multiplier?

$y = 15 · 5^{x}$

 $x$ $f(x)$ $-1$ $3$ $0$ $\mathbf{15}$ $1$ $75$ $2$ $\mathbf{375}$ $3$ $\mathbf{1875}$
1.  $x$ $f(x)$ $0$ $1$ $2$ $96.64$ $3$ $77.312$ $4$
 $x$ $f(x)$ $0$ $\mathbf{151}$ $1$ $\mathbf{120.8}$ $2$ $96.64$ $3$ $77.312$ $4$ $\mathbf{\approx 61.85}$
