A stepladder is diagrammed on a coordinate plane. The base of one leg of the stepladder is at the point​ (0,0), the base of the other leg is 12 ft to the​ right, and the top of the stepladder is 19.5 ft high.
a. Write a rule for function f to represent the​ stepladder, and state the domain.
b. Another stepladder has legs 14 ft apart and is 22.75 ft high. The base of its left leg is at the point​ (0,0). Write a rule for function g to represent this ladder and describe it as a transformation of f.
