But if we put a negative no. the square of it will be positive so the output will still be positive. Then why can’t we put negative no. someone pls explain.

#DMTips: When finding the domain, remember:

– The denominator (bottom) of a fraction cannot be zero
– The number under a square root sign must be positive in this section
