please help with question 1, 2 and 3 for discrete mathematics in computer science

or Problems 1-4 below, let the following three predicates be defined: F(x) : " x is a frog." G(x):"x is green." C(x):"x is cold-blooded." Select the expressions that are logically equivalent to the statement. (Check all that apply.) 1. Everything is a green frog. (a) x(F(x)G(x)) (b) x(F(x)G(x)) (c) x(F(x)G(x)) (d) x(G(x)F(x)) (e) x(G(x)F(x)) (f) x(F(x)G(x)) 2. If something is not green, then it can't be coldblooded. (a) x(C(x)G(x)) (b) x(G(x)C(x)) (c) x(G(x)C(x)) (d) x(G(x)C(x)) (e) x(G(x)C(x)) (f) x(C(x)G(x)) 3. Only frogs are green. (a) x(F(x)G(x)) (b) x(G(x)F(x)) (c) x(G(x)F(x)) (d) x(G(x)F(x)) (e) x(G(x)F(x)) (f) x(G(x)F(x))
