(20 pts) Observe the following information to answer the following set of questions:
f:{0,1}4{0,1}4 and f(x) is obtained by replacing the first bit of x with 1. For example, f(0100)=1100.
g:{0,1}4{0,1}4 and g(x) is obtained by removing the first bit of and placing the bit at the end. For example, g(1000)=0001.
a. Show the domain and co-domain for both f(on left) and g(on right)(map the functions).
b. Show the range for both functions and determine the cardinality for each.
c. Discuss if the functions are well-formed (why or why not).
d. For both functions f and g, show whether they are injective.
e. For functions f and g, show if they are surjective.
f. Based on the above, describe using logic formation if the functions are bijective.
