$f (x) = {(2)}^{x}$

Step 1

Write $f (x) = {(2)}^{x}$ as an equation.

$y = {(2)}^{x}$

Step 2

Remove parentheses.

$y = 2^{x}$

Step 3

Choose any value for $x$ that is in the domain to plug into the equation.

Step 4

Choose $0$ to substitute in for $x$ to find the ordered pair.

Step 4.1

Anything raised to $0$ is $1$ .

$y = 1$

Step 4.2

Use the $x$ and $y$ values to form the ordered pair.

$(0, 1)$

Step 5

Choose $1$ to substitute in for $x$ to find the ordered pair.

Step 5.1

Evaluate the exponent.

$y = 2$

Step 5.2

Use the $x$ and $y$ values to form the ordered pair.

$(1, 2)$

Step 6

Choose $2$ to substitute in for $x$ to find the ordered pair.

Step 6.1

Raise $2$ to the power of $2$ .

$y = 4$

Step 6.2

Use the $x$ and $y$ values to form the ordered pair.

$(2, 4)$

Step 7

These are three possible solutions to the equation.

$(0, 1), (1, 2), (2, 4)$
