all positive numbers and 0
option c

Answer:

C. All positive numbers and 0.

Step-by-step explanation:

We have been given a function \(y=\sqrt{x}\). We are asked to find the range of our given function.

We know that when a function is in form \(y=c\sqrt{ax+b}+k\), then the range of the square root function is all values of y greater than or equal to k.

We can rewrite our given function as:

\(y=\sqrt{x}+0\)

Since the value of k is 0, therefore, the range of our given function \(y\geq 0\) that is all positive numbers and 0.
