To find the limit of sqrt(4x^2-1) / x^2 as x approaches infinity, we can use the concept of limits.

First, we simplify the expression by dividing both the numerator and denominator by x^2:

sqrt(4x^2-1) / x^2 = (sqrt(4x^2-1)) / (x^2)

Next, as x approaches infinity, we can ignore the -1 term in the numerator since it becomes negligible compared to the large value of x^2.

Therefore, the expression simplifies to:

sqrt(4x^2) / x^2 = (2x) / x^2 = 2 / x

As x approaches infinity, the value of 2/x approaches 0.

Hence, the limit of sqrt(4x^2-1) / x^2 as x approaches infinity is 0.
