A. y ≥ -1
ExplanationStep 1: The minimum value of x^2 is 0. Step 2: So the minimum value of x^2 + -1 is -1, hence y ≥ -1. Step 3: A quadratic x^2 + c opens upward.
Step 1: x^2 की सबसे छोटी value 0 होती है। Step 2: इसलिए x^2 + -1 की सबसे छोटी value -1 होगी, यानी y ≥ -1। Step 3: Quadratic x^2 + c ऊपर की ओर खुलता है।
