can you help me with this? explain how to indicate?

[20 points] Determine whether the following candidate wavefunctions are normalizable over the indicated intervals. Normalize those that can be normalized. (Once you set up an integral, you may look up the solution in a table of your choosing and simply state the solution.) a. =e2x2 interval: (,) b. =ex interval: (0,) c. =eix interval: (0,2) =xex interval: (0,)
