I am clueless

Let f(x) = x2-7 and g(x) = x- 3 Find: i. (f º g )(x) [2] ii. (g º f) (x) [2] iii. f-1 (x) = g-1(x)

Thank you. I will send what I find

If I study, then I will not fail basket-weaving 101. If I do not play cards to often, then I will study. I failed basket-weaving 101. Therefore, I played cards too often. Is this statement valid (use truth tables to verify).

Consider the following open propositions over the universe U = {− 4,−2, 0, 1, 3, 5, 6, 8, 10} P(x): x ≥ 4 Q(x): x 2 = 25 R(x): s is a multiple of 2 Find on a single truth table the truth-values of the following. i. P(x ) ∧ R (x ) ii. [~ Q(x )] ∧ P(x )]
