Determine the truth value of each of these statements if the domain of each variable consists of all real numbers.a) ∀x∃y(x2 = y)
Answers
The statement ∀x∃y(x² = y) is true for all real numbers, as for each real number x, there exists a real number y such that x² = y.
How to determine the truth value of a statement?
The statement ∀x∃y(x² = y) is true as explained below:
For every real number x, there exists a real number y such that x² = y.
For example:
If x = 2, then y = 4 because 2² = 4.
If x = -3, then y = 9 because (-3)² = 9.
Since you can always find a real number y that satisfies the equation x² = y for any real number x, the statement is true for all real numbers in its domain.

The statement is true. If x and y are both real numbers, the statement is:
"for every x, there exist y such that "
This is true, because you can pick any real number, square it, and obtain another real number, y. The relation is not surjective, i.e. we will not use all possible values for y, but it doesn't matter. The statement is only asking to find a value for x^2, which we can always do.

Our equation is qudratic equation so the method we will follow to solve it is using the dicriminant :
- Let Δ be the dicriminant
- a=1
- b=2
- c=9
- Δ= 2²-4*1*9 =4-36=-32
- we notice that Δ≤0⇒x has no real solution
