If for any number N, f(N) is defined as the least integer that is greater than or equal to N^2, then what is the value of f(-1.5)?	Select the correct option:
A) -4	B) -3	C) 1	D) 2	E) 3
If N=-1.5, then N^2=2.25.   The least integer that is greater than or equal to 2.25 is 3, thus f(-1.5) = 2.25.   The answer is 3.
