Two real-valued functions are defined as f(x)=∣x−4∣ and g(x)=x−11, where x=1.
a. Compute f(0), g(0), f(5) and g(5).
b. For the inputs x=0 and x=5, determine for which input(s) the equality f(x)=g(x) holds. Show your calculations clearly.
c. Examine whether f(g(2)) is defined. If it is, find its value; if not, state the reason.
