Find the Domain and Range f(x)=3tan(2x-(3pi)/2)

$f (x) = 3 \tan (2 x - \frac{3 π}{2})$

Set the argument in $\tan (2 x - \frac{3 π}{2})$ equal to $\frac{π}{2} + π n$ to find where the expression is undefined.

$2 x - \frac{3 π}{2} = \frac{π}{2} + π n$ , for any integer $n$

Solve for $x$ .

Move all terms not containing $x$ to the right side of the equation.

Add $\frac{3 π}{2}$ to both sides of the equation.

$2 x = \frac{π}{2} + π n + \frac{3 π}{2}$

Combine the numerators over the common denominator.

$2 x = π n + \frac{π + 3 π}{2}$

Add $π$ and $3 π$ .

$2 x = π n + \frac{4 π}{2}$

Cancel the common factor of $4$ and $2$ .

Factor $2$ out of $4 π$ .

$2 x = π n + \frac{2 (2 π)}{2}$

Cancel the common factors.

Factor $2$ out of $2$ .

$2 x = π n + \frac{2 (2 π)}{2 (1)}$

Cancel the common factor.

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

Rewrite the expression.

$2 x = π n + \frac{2 π}{1}$

Divide $2 π$ by $1$ .

$2 x = π n + 2 π$

Divide each term in $2 x = π n + 2 π$ by $2$ and simplify.

Divide each term in $2 x = π n + 2 π$ by $2$ .

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

Simplify the left side.

Cancel the common factor of $2$ .

Cancel the common factor.

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

Divide $x$ by $1$ .

$x = \frac{π n}{2} + \frac{2 π}{2}$

Simplify the right side.

Cancel the common factor of $2$ .

Cancel the common factor.

$x = \frac{π n}{2} + \frac{2 π}{2}$

Divide $π$ by $1$ .

$x = \frac{π n}{2} + π$

The domain is all values of $x$ that make the expression defined.
