$(1, 11)$

Step 1

To find an exponential function, $f (x) = a^{x}$ , containing the point, set $f (x)$ in the function to the $y$ value $11$ of the point, and set $x$ to the $x$ value $1$ of the point.

$11 = a$

Step 2

Solve the equation for $a$ .

Rewrite the equation as $a^{1} = 11$ .

$a = 11$

Simplify.

$a = 11$

Step 3

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

$f (x) = {(11)}^{x}$
