Question

For which values of x does the expression square root of x+11 make sense?

Answer 1

all values greater than or equal to -11

Explanation:

For a square root to be a real number, the value under the square root must be positive. Therefore, all values of x must ensure that the value under the square root remains positive.

Answer 2

• Any real number x ≥ - 11

-------------------------------------------

The square root is defined when the expression under the root is not negative.

It is shown as:

• x + 11 ≥ 0 ⇒
• x ≥ - 11
