Two functions, f and g, map real numbers to integers. The functions f and g are defined as: f ( x ) = ⌊ x + 1 2 ⌋ g ( x ) = ⌈ x − 1 2 ⌉ Select the value for x such that f ( x ) ≠ g ( x ) .

Which statement is the contrapositive of: “If x = 4 , then 3 x = 12 .”

f(x) = |x| g(x) = -5x + 2 Select the correct value for g ∘ f ( 2 ) .

Select the value of the sum ∑ k = − 2 3 k 2 .

A = {1, 2, {3, 4}, {5, 6, 7}} Select the correct value for |A|.
