If f(x) is a greatest integer function, then f(-2. 5) is equal to

If f(x) = cos [pi]x + cos [pi x] , where [y] is the greatest integer function of y then f(pi/2) is equal to

If f:Irarr I be defined by f(x)=[x+1] ,where [.] denotes the greatest integer function then f(x) is equal to

If f(x)=cos[pi]x+cos[pi x], where [y] is the greatest integer function of y then f((pi)/(2)) is equal to

Let f:(6, 8)rarr (9, 11) be a function defined as f(x)=x+[(x)/(2)] (where [.] denotes the greatest integer function), then f^(-1)(x) is equal to

Let f : (4, 6)to(6, 8) be a function defined by f(x) x+[x/2] (where [.] denotes the greatest integer function), then f^(-1)(x) is equal to

Let f :(4,6) uu (6,8) be a function defined by f(x) = x+[(x)/(2)] where [.] denotes the greatest integer function, then f^(-1)(x) is equal to

Let f:(6, 8)rarr (9, 11) be a function defined as f(x)=x+[(x)/(2)] (where [.] denotes the greatest integer function), then f^(-1)(x) is equal to
