$(6, 0)$

Step 1

To find an exponential function, $f (x) = a^{x}$ , containing the point, set $f (x)$ in the function to the $y$ value $0$ of the point, and set $x$ to the $x$ value $6$ of the point.

$0 = a^{6}$

Step 2

Solve the equation for $a$ .

Step 2.1

Rewrite the equation as $a^{6} = 0$ .

$a^{6} = 0$

Step 2.2

Take the specified root of both sides of the equation to eliminate the exponent on the left side.

$a = \pm \sqrt[6]{0}$

Step 2.3

Simplify $\pm \sqrt[6]{0}$ .

Step 2.3.1

Rewrite $0$ as $0^{6}$ .

$a = \pm \sqrt[6]{0^{6}}$

Step 2.3.2

Pull terms out from under the radical, assuming positive real numbers.

$a = \pm 0$

Step 2.3.3

Plus or minus $0$ is $0$ .

$a = 0$

Step 3

Substitute each value for $a$ back into the function $f (x) = a^{x}$ to find each possible exponential function.

$f (x) = {(0)}^{x}$
