# How do you find the domain and range of #P(r)= 3/(sqrtr)#?

Domain 0f

Range 0f

We need to make sure that the value of r is not equal to 0 or any negative numbers since it would not produce real values. As we know, anything divided by 0 is undefined or infinity, and the square root of negative numbers is not real.

To find the domain of ( P(r) = \frac{3}{\sqrt{r}} ), solve for ( r ) in the denominator. The domain is all real numbers greater than zero.

To find the range, consider the behavior of the function as ( r ) approaches positive infinity and as ( r ) approaches zero. The range is all real numbers greater than zero.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
