Use the predicate specifications(x, y): x beats yF (x): x is an (American) football teamQ(x, y): x is quarterback of yL(x,y): x loses to yand the constant symbols c: Wildcats, j: Jayhawks to translate the following into predicate logic.(a)Every football team has a quarterback.(b)If the Jayhawks beat the Wildcats, then the Jayhawks do not lose to every football team.(c)The Wildcats beat some team, which beat the Jayhawks.

Answer 1

a) ∀y∃x(Q(x, y))
