$\"\"$	$\"\"$	$\"\"$	$\"\"$	$\"\"$	$\"\"$
$\"\"$	$\"\"$	$\"\"$	$\"\"$	$\"\"$	$\"\"$

The general exponential function is in the form of $\"\"$ .

From the table, substitute $\"\"$ and $\"\"$ .

$\"\"$

Thus, the exponential function is $\"\"$ .

From the table, substitute $\"\"$ and $\"\"$ in the above equation.

$\"\"$

Substitute the values of $\"\"$ and $\"\"$ in $\"\"$ .

$\"\"$

Therefore, the exponential function is $\"\"$ .
