Answer #1

Question 9

# Graph l shows as f increase Z decreases, which is not the dependency.

# Graph III shows as f increase Z remains constant, this is not true.

# Graph IV shows linear dependency of Z and f , this is not true.

# Graph ll shows a non linear increase of Z with frequency f, which is the actual dependency.
