The domain of the function
consists of all the values of
for which the expression under the square root is non-negative. This means we need the inside,
, to be greater than or equal to zero, leading us to
.
To visualize this, imagine a number line starting at 10. All the numbers to the right of and including 10 are in the domain of the function. This is why option A,
, is the correct choice.
As you explore this function, picture a curve that starts at the point (10,0) and stretches infinitely to the right. Because a square root cannot produce negative numbers, the function is only defined from 10 onwards. So, anytime you encounter a similar function, just remember to set that expression inside the square root greater than or equal to zero to find the domain!
