Question

How do i set up this?
find the domain of square root of 2x-10 by finding the intervals on the real number line?

Answer 1

the domain is the set of all Xs that are valid since the equation is \[\sqrt{2x-10}\] and you can not have a - square root you need to find all values of X that satisfy the equation:
\[2x -10 \ge 0 \] when you solve for X on that equation you get \[x \ge 5\] so the domain of this function is \[x \ge 5\]

Answer 2

Thanks!!
