Statement -1: f:A→B and g: B→C are functions then (gof)−1=f−1og−1
Statement-2: f:A→B and g: B→C are bijections then f−1,g−1 are also bijections
Statement -I, Statement -II are correct, Statement -II is correct explanation to Statement –I
Statement -I, Statement -II are correct, Statement -II is not correct explanation to Statement – I
Statement -I is true, Statement -II is false
Statement -I is false, Statement -II is true
Function need not be invertible.
