C.
all positive numbers and 0
D.
all negative numbers

Answer 1

all positive numbers and 0
option c

Answer 2

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.
