This scenario is mostly found during a store sale where they offer discounts.

Assuming: Original price = 90 ; discount rate = 25%

Discount value = Original price * discount rate
Discount value = 90 x 25% = 22.50

Since 25% is the discount, you only need to pay 75% of the original price.

Discounted Price = original price * (100-25)% = 90 x 75% = 67.50

A 2-column table has 4 rows. The first column is labeled x with entries negative 1, 0, 1, 2. The second column is labeled f (x)

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}
