Question

How do you find the domain of f(p) = sqrt (2 - sqrt(p))?

Answer 1

Well we know that we cant have a negative value in the square root

So \(2-\sqrt{ p} \geq 0\)

So lets solve for p and find our domain or in other words the condition that will make this equation true
\[ 2-\sqrt{p} \geq 0\]
\[2 \geq \sqrt {p}\]
\[4 \geq p\]

Answer 2

Thank you so much! This make so much sense
