Find the Exponential Function (1,-3)

$(1, - 3)$

Step 1

To find an exponential function, $f (x) = a^{x}$ , containing the point, set $f (x)$ in the function to the $y$ value $- 3$ of the point, and set $x$ to the $x$ value $1$ of the point.

$- 3 = a$

Step 2

Solve the equation for $a$ .

Rewrite the equation as $a^{1} = - 3$ .

$a = - 3$

Simplify.

$a = - 3$

Step 3

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

$f (x) = {(- 3)}^{x}$
