Find the intervals on which the function is continuous.
-$$y = \frac { 3 } { x + 7 } - 3 x$$
A) discontinuous only when $x = - 10$
B) discontinuous only when $x = - 7$
C) discontinuous only when $x = 7$
D) continuous everywhere

The function $y = \frac { 3 } { x + 7 } - 3 x$ is continuous everywhere except where the denominator of the fraction equals zero, which occurs when $x + 7 = 0$, or $x = -7$. Therefore, the function is discontinuous only when $x = -7$.
