Here, you have to determine values of f(x) for negative domain. Domain are those values of x for which function is defined. Since the function is a polynomial, every value of x∈R is defined for f(x). And for every negative value of x, f(x) will always be positive because x is squared and square of negative real number is always positive. 0 is neither negative nor positive. Therefore, zero is not included in negative domain. If you plug say x= -0.00000956, f(x) will be greater than 1 because square of x will never be negative. Thus, the range will always be positive or greater than equal to 1. Therefore, y≥1
