Find the Domain and Range y=tan(pi/2x)

$y = \tan (\frac{π}{2} x)$

Set the argument in $\tan (\frac{π}{2} x)$ equal to $\frac{π}{2} + π n$ to find where the expression is undefined.

$\frac{π}{2} x = \frac{π}{2} + π n$ , for any integer $n$

Solve for $x$ .

Multiply both sides of the equation by $\frac{2}{π}$ .

$\frac{2}{π} (\frac{π}{2} x) = \frac{2}{π} (\frac{π}{2} + π n)$

Simplify both sides of the equation.

Simplify the left side.

Simplify $\frac{2}{π} (\frac{π}{2} x)$ .

Combine $\frac{π}{2}$ and $x$ .

$\frac{2}{π} \cdot \frac{π x}{2} = \frac{2}{π} (\frac{π}{2} + π n)$

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{2}{π} \cdot \frac{π x}{2} = \frac{2}{π} (\frac{π}{2} + π n)$

Rewrite the expression.

$\frac{1}{π} (π x) = \frac{2}{π} (\frac{π}{2} + π n)$

Cancel the common factor of $π$ .

Factor $π$ out of $π x$ .

$\frac{1}{π} (π (x)) = \frac{2}{π} (\frac{π}{2} + π n)$

Cancel the common factor.

$\frac{1}{π} (π x) = \frac{2}{π} (\frac{π}{2} + π n)$

Apply the distributive property.

$x = \frac{2}{π} \cdot \frac{π}{2} + \frac{2}{π} (π n)$

Cancel the common factor of $2$ .

Cancel the common factor.

$x = \frac{2}{π} \cdot \frac{π}{2} + \frac{2}{π} (π n)$

Rewrite the expression.

$x = \frac{1}{π} π + \frac{2}{π} (π n)$

Cancel the common factor of $π$ .

Factor $π$ out of $π n$ .

$x = 1 + \frac{2}{π} (π (n))$

Cancel the common factor.

$x = 1 + \frac{2}{π} (π n)$

Rewrite the expression.

$x = 1 + 2 n$

Reorder $1$ and $2 n$ .
