Domain: (7x + 2 \geq 0) since the square root of a negative number is undefined in the real number system. [ \text{Domain: } x \geq -\frac{2}{7} ]

Range: The square root of any real number is non-negative. [ \text{Range: } f(x) \geq 0 ]

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
