Identify Independent and Dependent in Functions

Identify the Independent and Dependent Variables, then write a rule in function notation.
A baker spends $6 on ingredients for each cake he bakes.

• Ind: Cost
  Dep: Cakes
  f(c) = 6c

• Ind: Cakes
  Dep: Cost
  f(c) = c + 6

• Ind: Cost
  Dep: Cakes
  f(c) = c + 6

• Ind: Cakes
  Dep: Cost
  f(c) = 6c
