$f (2) = \frac{t (t - 3)}{t - 2} + \frac{4 - t}{t - 2}$

Step 1

Replace the variable $t$ with $2$ in the expression.

$f (2) = \frac{(2) ((2) - 3)}{(2) - 2} + \frac{4 - (2)}{(2) - 2}$

Step 2

Subtract $2$ from $2$ .

$f (2) = \frac{(2) ((2) - 3)}{0} + \frac{4 - (2)}{(2) - 2}$

Step 3

The expression contains a division by $0$ . The expression is undefined.
