EXERCISE2.5.4: Composition of onto and one-to-one functions. Let f: X Y and g: Y Z be two functions. (a) Is it possible that f is not onto and g o fis onto? Justify your answer. If the answer is yes, give a specific example for f and g. (b) Is it possible that g is not onto and g o f is onto? Justify your answer. If the answer is 'yes, give a specific example for fand g Is it possible that f is not one-to-one and g o f is one-to-one? Justify your answer. If the answer is 'yes, give a specific example for f and g it possible that g is not one-to-one and g o fis one-to-one? Justify your answer. If the answer is 'yes', give a specific example for f and g d Is
