What is the range of the function?

all real numbers less than or equal to 4

all real numbers less than or equal to - 3

all real numbers greater than or equal to 4

all real numbers greater than or equal to - 3

The range of the graph is all real numbers greater than or equal to 0."

Step-by-step explanation:

For a square root function

we see that x values has to be greater than or equal to 0 or else we get negative roots, which is not possible.

So domain (x-values for which function is defined) will be x ≥ 0

We can't get any negative answers from square root functions, so the range would be anything greater than or equal to zero.

So range (y-values for which function is defined) will be y ≥ 0

looking at the answer choices, the last one is right ...

The range is all real numbers less than or equal to 4
