Which expression should you insert into each function?

DRAG DROP
You are validating user input by using JavaScript and regular expressions.
A group of predefined regular expressions will validate two input fields:
An email address in a function named validateEmail (for example, [email protected])
A nine-digit number that allows optional hyphens after the second and fifth character in a function named
validateSSN(for example, 555555555 or 555-55-5555)
You need to use the correct expression to validate the input.
Which expression should you insert into each function? (To answer, drag the appropriate regular expression
statement to the correct location. Each regular expression statement may be used once, more than once, or not
at all. You may need to drag the split bar between panes or scroll to view content.)
