The decay factor of the exponential function given in the table is of $\frac{2}{3}$ .

<h3>What is an exponential function?</h3>

A decaying exponential function is modeled by:

$A(t) = A(0)(1 - r)^t$

In which:

A(0) is the initial value.

r is the decay rate, as a decimal.

In this problem, we have that when x increases by 1, y decreases by a factor of 3, hence the decay rate r is found as follows:

$1 - r = \frac{1}{3}$

$r = 1 - \frac{1}{3}$

$r = \frac{2}{3}$
