To find the limit of (3x + 9) / sqrt(2x^2 + 1) as x approaches infinity, we can simplify the expression by dividing both the numerator and denominator by x. This gives us (3 + 9/x) / sqrt(2 + 1/x^2).

As x approaches infinity, the term 9/x approaches 0, and the term 1/x^2 also approaches 0. Therefore, the expression simplifies to 3 / sqrt(2).

Hence, the limit of (3x + 9) / sqrt(2x^2 + 1) as x approaches infinity is 3 / sqrt(2).

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.
