$f (7) = \frac{s^{3} - 343}{s^{2} - 49}$

Step 1

Replace the variable $s$ with $7$ in the expression.

$f (7) = \frac{{(7)}^{3} - 343}{{(7)}^{2} - 49}$

Step 2

Raise $7$ to the power of $2$ .

$f (7) = \frac{{(7)}^{3} - 343}{49 - 49}$

Step 3

Subtract $49$ from $49$ .

$f (7) = \frac{{(7)}^{3} - 343}{0}$

Step 4

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