If lambda is an integer and alpha, beta are the roots of 4x^(2) - 16x + lambda/4 such that 1 lt alpha lt 2 and 2 lt beta lt 3 , then how many values can 'lambda ' take ?

If f(x)= {(|1-4x^2|,; 0 lt= x lt 1), ([x^2-2x],; 1 lt= x lt 2):} , where [.] denotes the greatest integer function, then f(x) is

Statement - 1 : If x gt 1 then log_(10)x lt log_(3)x lt log_(e )x lt log_(2)x . Statement - 2 : If 0 lt x lt 1 , then log_(x)a gt log_(x)b implies a lt b .

Let Z be the set of integers. If A= { x in Z : 2^((x+2)(x^(2)-5x+6)) =1} and B={x in Z: -3 lt 2x -1 lt 9}, then the number of subsets of the set A xx B , is
