Select the value of the sum ∑k=-23k2{“version”:”1.1″,”math”:”∑k=-23k2″}  

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

Let x, y and z be arbitrary integers. Determine if the statement is true or false. If true, prove it. If false, provide a counterexample. If x | (y+z), then x | y or x | z.  

Two functions, f and g, map real numbers to integers. The functions f and g are defined as: f(x)=x+12g(x)=x-12{“version”:”1.1″,”math”:”f(x)=x+12g(x)=x-12″} Select the value for x such that f ( x ) ≠ g ( x ) .

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