Question

Find domain of given function.

y = √px, ( p > 0).

Answer 1

y = \(\sqrt{px}, p>0\)

For domain of function y, we required

px \(\geq\) 0

⇒ x \(\geq\) \(\frac0p\) (\(\because\) p > 0, so on dividing sign remains same)

⇒ x \(\geq0\)

Hence, domain of function y = \(\sqrt{px},p>0 \,is \,x \in [0,\infty )\)
