Find Where Undefined/Discontinuous y=(7x-2)/(x+5)

$y = \frac{7 x - 2}{x + 5}$

Set the denominator in $\frac{7 x - 2}{x + 5}$ equal to $0$ to find where the expression is undefined.

$x + 5 = 0$

Subtract $5$ from both sides of the equation.

$x = - 5$

The equation is undefined where the denominator equals $0$ , the argument of a square root is less than $0$ , or the argument of a logarithm is less than or equal to $0$ .

$x = - 5$
