Find the quantifier which best describes the variable of the open sentence

Find the quantifier which best describes the variable of the open sentence \( x^{2}+2 \geq 0 \)

  • A. Universal.
  • B. Existential.
  • C. Neither (a) nor (b)
  • D. Does not exist.

Step-by-step solution

The inequality x^2 + 2 ≥ 0 holds for all real numbers x because x^2 ≥ 0, so x^2 + 2 ≥ 2 > 0. Therefore, the universal quantifier 'for all x' makes the statement true.
