How do you solve x^2-4X-12=0

Pepsi [2]

x² - 4x - 12 = 0

Factor the left side: (x + 2) · (x - 6) = 0

The equation is true if either factor is zero.

If (x + 2) = 0 then x = -2 .

If (x - 6) = 0 then x = 6 .

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:

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

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

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