Question

√x<4 A.20 B.12 C.2 D.-1 E.5. F. No solution

Answer 1

We know that for √x to be meaningful, we must have x ≥ 0.

If we square both sides of the inequality, we have
x < 4²
x < 16

Thus the whole solution is
0 ≤ x < 16

The following choices are valid solutions to the inequality:
B. 12
C. 2
E. 5
