Domain is any value that x can take and have h(x) still make sense. Problems ususally come when you have fractions (can't divide by zero), when you take a square root (can't take a square root of a negative number) or when you have special functions (like logarithms).
Here, there are no restrictions. x can be anything.
Take away 2 from any number, you can always square the remainder.
The range (or image) will be restricted: once you take any number and square it, the result will always be positive.

the domain is any real number.
Domain is what the x value can be. In this equation, you plug any value of x as long as x is a real number.

Since nothing that x could be would make it illegal, D={all real numbers}.
