To find the domain and range of ( y = \sqrt{x^2 + 2x + 3} ):

Domain: Since the expression under the square root must be nonnegative, we need to find the values of ( x ) that make ( x^2 + 2x + 3 \geq 0 ).
 To determine the domain, solve the quadratic inequality ( x^2 + 2x + 3 \geq 0 ).

Range: Since the square root function returns nonnegative values, the range of ( y ) will be all nonnegative real numbers.
 Hence, the range of ( y ) is ( [0, +\infty) ).

When evaluating a onesided 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.
