Answer:
Here, the condition is x ≠ -3
Therefore, we'll compute an equation under which x being 3 will not possible in order to evaluate the equation.
One of such equation is :
[tex]y = \frac{x - 3}{x + 3}[/tex]
With the condition that x ≠ -3, because then the denominator will become ∞ and hence we won't be able to evaluate the equation.
