You can put this solution on YOUR website! Determine the values for the variable that will make each expression a real number.
------
For each, the radicand cannot be negative.
-----------------
The problems are:
√ 2x-1
Solve: 2x-1 >= 0
2x >= 1
x >= 1/2
-----------------
√ 2x-10
Solve: 2x-10 >= 0
2x >= 10
x >= 5
---------------------------------------
√ 2x^2
2x^2 >= 0
x^2 >= 0
x is All Real Numbers
-------------------------------------------------------
Etc.
