To evaluate the limit of 3x^2+4x-5 as x approaches 5, we substitute 5 for x in the expression. This gives us 3(5)^2 + 4(5) - 5. Simplifying further, we have 3(25) + 20 - 5, which equals 75 + 20 - 5. Combining like terms, we get 95 - 5, resulting in a final answer of 90.

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.
