Answer: The domain of function y=\sqrt{x} is [0,\infty).

Explanation:

The given function is,

y=\sqrt{x}

The domain is the set of all possible inputs. For a function the domain is all the possible value of x for which the function is defined.

The given function is a root function. We know that the root of of a negative number is not defined or the vaye of y is not a real number for x<0.

Therefore the given function is defined for all positive values of x and the domain of the given function is all values which are greater than or equal to 0 in interval notation it is written as [0,\infty).

Two hundred fifty-six thousand, seven hundred eighty can be written as 256,780.

8. Eighty-five thousand, nine

This can be written as:

85,000+9 = 85,009

Eighty-five thousand, nine can be written as 85,009.

9. Two hundred thirty-eight thousand, eight hundred fifty-seven miles

Inessa [10]
So if 29 students rode in cars, we can subtract 29 from 237 because we don't need to know about the people in the cars, which means that 208 students rode on buses. If there were 8 buses, the we need to divide 208 by 8 which makes 26 students per bus.

I hope this helps!
