Question

Which statement is true about the function f(x)= sqrt x ? The domain of the graph is all real numbers. The range of the graph is all real numbers. The domain of the graph is all real numbers less than or equal to 0. The range of the graph is all real numbers greater than or equal to 0.

Answer 1

Answer:

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

Step-by-step explanation:

For a square root function  $f(x)=\sqrt{x}$

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..
