$\"\"$

\

The function is $\"\"$ .

\

Replace $\"\"$ with y.

\

$\"\"$

\

Next switch x for y and y for x.

\

$\"\"$ $\"\"$

\

Next solve for y:

\

$\"\"$

\

$\"\"$ (Multiply: $\"\"$ )

\

$\"\"$ (Multiply each side by 2)

\

$\"\"$ (Apply distributive property: $\"\"$ )

\

$\"\"$ (Cancel common terms)

\

$\"\"$ (Multiply: $\"\"$ ) $\"\"$

\

$\"\"$ (Subtract 2 from each side)

\

$\"\"$ (Apply additive inverse property: $\"\"$ )

\

$\"\"$ (Apply additive identity property: $\"\"$ )

\

The value of $\"\"$ . $\"\"$

\

Write in function notation, using $\"\"$ to represent the inverse of the function f.

\

$\"\"$

\

Substitute $\"\"$ in above function,

\

$\"\"$ . $\"\"$

\

The inverse function of $\"\"$ is $\"\"$ .
