Correct Answer : Option (B) : Two zeroes at infinity
Explanation : The formula to calculate a number of zeroes at infinity is P - Z. Here, P and Z are the number of poles and zeroes in a given transfer function.
We know that poles are calculated by equating the denominator to zero, and zeroes are calculated by equating the numerator to zero. So, for the above given transfer function, we get:
P = 3
Z = 1
So, the number of zeroes at infinity = 3 - 1 = 2
