square root functions → f(x)= √x
Constant second differences between xvalues for for evenly spaces yvalues. 
rationalize the denominator → when an expression is rewritten so that there are no radicals in any denominator and no denominators in any radicals

inverse functions → a set of ordered pairs obtained by switching the coordinates in a relation

radicand → radicals that have the same radicand
